Ice hockey (or simply hockey in North America) is a team sport played on ice skates, usually on an Ice rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. Two opposing teams use ice hockey sticks to control, advance, and shoot a vulcanized rubber hockey puck into the other team's net. Each goal is worth one point. The team with the highest score after an hour of playing time is declared the winner; ties are broken in overtime or a shootout. In a formal game, each team has six Ice skating on the ice at a time, barring any penalties, including a goaltender. It is a full contact game and one of the more physically demanding team sports.
The modern sport of ice hockey was developed in Canada, most notably in Montreal, where the first indoor game was played on March 3, 1875. It draws influence from shinty which originated in Scotland, as well as field hockey which originated in England. Some characteristics of ice hockey, such as the length of the ice rink and the use of a puck, have been retained to this day. Amateur ice hockey leagues began in the 1880s, and professional ice hockey originated around 1900. The Stanley Cup, emblematic of ice hockey club supremacy, was initially commissioned in 1892 as the "Dominion Hockey Challenge Cup" and was first awarded in 1893 to recognise the Canadian amateur champion and later became the championship trophy of the National Hockey League (NHL). In the early 1900s, the Canadian rules were adopted by the , in Paris, France, the precursor to the International Ice Hockey Federation (IIHF). The sport was played for the first time at the Olympics during the 1920 Summer Games—today it is a mainstay at the Winter Olympics. In 1994, ice hockey was officially recognized as Canada's national winter sport.
While women also played during the game's early formative years, it was not until organizers began to officially remove body checking from female ice hockey beginning in the mid-1980s that it began to gain greater popularity, which by then had spread to Europe and a variety of other countries. The IIHF Women's World Championship was held in 1990, and women's play was introduced into the Olympics in 1998.
Ice hockey is played on a hockey rink. During normal play, there are six players on ice skates on the ice per side, one of them being the goaltender. The objective of the game is to score goals by shooting a hard Vulcanization rubber disc, the hockey puck, into the opponent's goal net at the opposite end of the rink. The players use their sticks to pass or shoot the puck.
With certain restrictions, players may redirect the puck with any part of their body. Players may not hold the puck in their hand and are prohibited from using their hands to pass the puck to their teammates unless they are in the defensive zone. Players can knock a puck out of the air with their hands to themselves. Players are prohibited from kicking the puck into the opponent's goal, though unintentional redirections off their body or equipment, including skates, are permitted. Players may not intentionally bat the puck into the net with their hands or any part of their body.
Hockey is an off-side game, meaning that forward passes are allowed, unlike in rugby. Before the 1930s, hockey was an on-side game, meaning that only backward passes were allowed. Those rules emphasized individual stick-handling to drive the puck forward. With the arrival of offside rules, the forward pass transformed hockey into a true team sport, where individual performance diminished in importance relative to team play, which could now be coordinated over the entire surface of the ice as opposed to merely rearward players.
The six players on each team are typically divided into three forwards, two defencemen, and one goaltender. The term skaters typically applies to all players except goaltenders. The forward positions consist of a centre and two wingers: a left wing and a right wing. Forwards often play together as units or lines, with the same three forwards always playing together. The defenceman usually stay together as a pair generally divided between left and right. Left and right side wingers or defencemen are generally positioned on the side on which they carry their stick. A substitution of an entire unit at once is called a line change. Teams typically employ alternate sets of forward lines and defensive pairings when short-handed or on a power play. The goaltender stands in a, usually blue, semi-circle called the crease in the defensive zone keeping pucks out of the goal. Substitutions are permitted at any time during the game, although during a stoppage of play the home team is permitted the final change. When players are substituted during play, it is called changing on the fly. An NHL rule added in the 2005–06 season prevents a team from making any player substitutions after they ice the puck.
The boards surrounding the ice help keep the puck in play and they can also be used as tools to play the puck. Players are permitted to bodycheck opponents into the boards to stop progress. The referees, linesmen and the outsides of the goal are "in play" and do not stop the game when the puck or players either bounce into or collide with them. Play can be stopped if the goal is knocked out of position. Play often proceeds for minutes without interruption. After a stoppage, play is restarted with a faceoff. Two players face each other and an official drops the puck to the ice, where the two players attempt to gain control of the puck. Markings (circles) on the ice indicate the locations for the faceoff and guide the positioning of players.
Three major rules of play in ice hockey limit the movement of the puck: offside, icing, and the puck going out of play.
Under IIHF rules, each team may carry a maximum of 20 players and two goaltenders on their roster. NHL rules restrict the total number of players per game to 18, plus two goaltenders. In the NHL, the players are usually divided into four lines of three forwards, and into three pairs of defencemen. On occasion, teams may elect to substitute an extra defenceman for a forward. The seventh defenceman may play as a substitute defenceman, spend the game on the bench, or if a team chooses to play four lines then this seventh defenceman may see ice-time on the fourth line as a forward.
If a tie occurs in tournament play, as well as in the NHL playoffs, North Americans favour sudden death overtime, in which the teams continue to play twenty-minute periods until a goal is scored. Up until the 1999–2000 season, regular-season NHL games were settled with a single five-minute sudden death period with five players (plus a goalie) per side, with both teams awarded one point in the standings in the event of a tie. With a goal, the winning team would be awarded two points and the losing team none (just as if they had lost in regulation). The total elapsed time from when the puck first drops, is about 2 hours and 20 minutes for a 60-minute game.
From the 1999–2000 until the 2003–04 seasons, the National Hockey League decided ties by playing a single five-minute sudden-death overtime period with each team having four skaters per side (plus the goalie). In the event of a tie, each team would still receive one point in the standings but in the event of a victory the winning team would be awarded two points in the standings and the losing team one point. The idea was to discourage teams from playing for a tie, since previously some teams might have preferred a tie and 1 point to risking a loss and zero points. The exception to this rule is if a team opts to pull their goalie in exchange for an extra skater during overtime and is subsequently scored upon (an empty net goal), in which case the losing team receives no points for the overtime loss. Since the 2015–16 season, the single five-minute sudden-death overtime session involves three skaters on each side. Since three skaters must always be on the ice in an NHL game, the consequences of penalties are slightly different from those during regulation play; any penalty during overtime that would result in a team losing a skater during regulation instead causes the other side to add a skater. Once the penalized team's penalty ends, the penalized skater exits the penalty box and the teams continue at 4-on-4 until the next stoppage of play, at which point the teams return to three skaters per side. International play and several North American professional leagues, including the NHL (in the regular season), now use an overtime period identical to that from 1999–2000 to 2003–04 followed by a penalty shootout. If the score remains tied after an extra overtime period, the subsequent shootout consists of three players from each team taking penalty shots. After these six total shots, the team with the most goals is awarded the victory. If the score is still tied, the shootout then proceeds to sudden death. Regardless of the number of goals scored by either team during the shootout, the final score recorded will award the winning team one more goal than the score at the end of regulation time. In the NHL if a game is decided in overtime or by a shootout the winning team is awarded two points in the standings and the losing team is awarded one point. Ties no longer occur in the NHL.
Overtime in the NHL playoffs differs from the regular season. In the playoffs there are no shootouts. If a game is tied after regulation, then a 20-minute period of 5-on-5 sudden-death overtime will be added. If the game is still tied after the overtime, another period is added until a team scores, which wins the match. Since 2019, the IIHF World Championships and the gold medal game in the Olympics use the same format, but in a 3-on-3 format.
A two-minute minor penalty is often charged for lesser infractions such as tripping, elbowing, roughing, high-sticking, delay of the game, too many players on the ice, boarding, illegal equipment, charging (leaping into an opponent or body-checking him after taking more than two strides), holding, holding the stick (grabbing an opponent's stick), interference, hooking, slashing, kneeing, unsportsmanlike conduct (arguing a penalty call with referee, extremely vulgar or inappropriate verbal comments), "butt-ending" (striking an opponent with the knob of the stick), "spearing" (jabbing an opponent with the blade of the stick), or cross-checking. As of the 2005–2006 season, a minor penalty is also assessed for diving, where a player embellishes or simulates an offence. More egregious fouls may be penalized by a four-minute double-minor penalty, particularly those that injure the victimized player. These penalties end either when the time runs out or when the other team scores during the power play. In the case of a goal scored during the first two minutes of a double-minor, the penalty clock is set down to two minutes upon a score, effectively expiring the first minor penalty.
Five-minute major penalties are called for especially violent instances of most minor infractions that result in intentional injury to an opponent, or when a minor penalty results in visible injury (such as bleeding), as well as for fighting. Major penalties are always served in full; they do not terminate on a goal scored by the other team. Major penalties assessed for fighting are typically offsetting, meaning neither team is short-handed and the players exit the penalty box upon a stoppage of play following the expiration of their respective penalties. The foul of boarding (defined as "checking an opponent in such a manner that causes the opponent to be thrown violently in the boards") is penalized either by a minor or major penalty at the discretion of the referee, based on the violent state of the hit. A minor or major penalty for boarding is often assessed when a player checks an opponent from behind and into the boards.
Some varieties of penalty do not require the offending team to play a man short. Concurrent five-minute major penalties in the NHL usually result from fighting. In the case of two players being assessed five-minute fighting majors, both the players serve five minutes without their team incurring a loss of player (both teams still have a full complement of players on the ice). This differs with two players from opposing sides getting minor penalties, at the same time or at any intersecting moment, resulting from more common infractions. In this case, both teams will have only four skating players (not counting the goaltender) until one or both penalties expire (if one penalty expires before the other, the opposing team gets a power play for the remainder of the time); this applies regardless of current pending penalties. In the NHL, a team always has at least three skaters on the ice. Thus, ten-minute misconduct penalties are served in full by the penalized player, but his team may immediately substitute another player on the ice unless a minor or major penalty is assessed in conjunction with the misconduct (a two-and-ten or five-and-ten). In this case, the team designates another player to serve the minor or major; both players go to the penalty box, but only the designee may not be replaced, and he is released upon the expiration of the two or five minutes, at which point the ten-minute misconduct begins. In addition, game misconducts are assessed for deliberate intent to inflict severe injury on an opponent (at the officials' discretion), or for a major penalty for a stick infraction or repeated major penalties. The offending player is ejected from the game and must immediately leave the playing surface (he does not sit in the penalty box); meanwhile, if an additional minor or major penalty is assessed, a designated player must serve out of that segment of the penalty in the box (similar to the above-mentioned "two-and-ten"). In some rare cases, a player may receive up to nineteen minutes in penalties for one string of plays. This could involve receiving a four-minute double-minor penalty, getting in a fight with an opposing player who retaliates, and then receiving a game misconduct after the fight. In this case, the player is ejected and two teammates must serve the double-minor and major penalties. A penalty shot is awarded to a player when the illegal actions of another player stop a clear scoring opportunity, most commonly when the player is on a breakaway. A penalty shot allows the obstructed player to pick up the puck on the centre red-line and attempt to score on the goalie with no other players on the ice, to compensate for the earlier missed scoring opportunity. A penalty shot is also awarded for a defender other than the goaltender covering the puck in the goal crease, a goaltender intentionally displacing his own goal posts during a breakaway to avoid a goal, a defender intentionally displacing his own goal posts when there is less than two minutes to play in regulation time or at any point during overtime, or a player or coach intentionally throwing a stick or other object at the puck or the puck carrier and the throwing action disrupts a shot or pass play.
Officials also stop play for puck movement violations, such as using one's hands to pass the puck in the offensive end, but no players are penalized for these offences. The sole exceptions are deliberately falling on or gathering the puck to the body, carrying the puck in the hand, and shooting the puck out of play in one's defensive zone (all penalized two minutes for delay of game).
In the NHL, a unique penalty applies to the goalies. The goalies now are forbidden to play the puck in the "corners" of the rink near their own net. This will result in a two-minute penalty against the goalie's team. Only in the area in front of the goal line and immediately behind the net (marked by two red lines on either side of the net) can the goalie play the puck.
An additional rule that has never been a penalty, but was an infraction in the NHL before recent rules changes, is the Two-line pass. Prior to the 2005–06 NHL season, play was stopped when a pass from inside a team's defending zone crossed the centre line, with a face-off held in the defending zone of the offending team. Now, the centre line is no longer used in the NHL to determine a two-line pass infraction, a change that the IIHF had adopted in 1998. Players are now able to pass to teammates who are more than the blue and centre ice red line away.
The NHL has taken steps to speed up the game of hockey and create a game of finesse, by reducing the number of illegal hits, fights, and "clutching and grabbing" that occurred in the past. Rules are now more strictly enforced, resulting in more penalties, which provides more protection to the players and facilitates more goals being scored. The governing body for United States' amateur hockey has implemented many new rules to reduce the number of stick-on-body occurrences, as well as other detrimental and illegal facets of the game ("zero tolerance").
In men's hockey, but not in women's, a player may use his hip or shoulder to hit another player if the player has the puck or is the last to have touched it. This use of the hip and shoulder is called body checking. Not all physical contact is legal—in particular, hits from behind, hits to the head and most types of forceful stick-on-body contact are illegal. A delayed penalty call occurs when an offence is committed by the team that does not have possession of the puck. In this circumstance the team with possession of the puck is allowed to complete the play; that is, play continues until a goal is scored, a player on the opposing team gains control of the puck, or the team in possession commits an infraction or penalty of their own. Because the team on which the penalty was called cannot control the puck without stopping play, it is impossible for them to score a goal. In these cases, the team in possession of the puck can pull the goalie for an extra attacker without fear of being scored on. It is possible for the controlling team to mishandle the puck into their own net. If a delayed penalty is signalled and the team in possession scores, the penalty is still assessed to the offending player, but not served. In 2012, this rule was changed by the United States' National Collegiate Athletic Association (NCAA) for college level hockey. In college games, the penalty is still enforced even if the team in possession scores.
Officials are selected by the league they work for. Amateur hockey leagues use guidelines established by national organizing bodies as a basis for choosing their officiating staffs. In North America, the national organizing bodies Hockey Canada and USA Hockey approve officials according to their experience level as well as their ability to pass rules knowledge and skating ability tests. Hockey Canada has officiating levels I through VI. USA Hockey has officiating levels 1 through 4.
The goaltender carries a stick of a different design, with a larger blade and a wide, flat shaft. This stick is primarily intended to block shots, but the goaltender may use it to play the puck as well.
Compared to athletes who play other sports, ice hockey players are at higher risk of overuse injuries and injuries caused by early sports specialization by teenagers.
According to the Hughston Health Alert, prior to the widespread use of helmets and face cages, "Lacerations to the head, scalp, and face are the most frequent types of injury in."
One of the leading causes of head injury is body checking from behind. Due to the danger of delivering a check from behind, many leagues – including the NHL – have made this a major and game misconduct penalty. Another type of check that accounts for many of the player-to-player contact concussions is a check to the head resulting in a misconduct penalty (called "head contact"). In recent years, the NHL has implemented new rules which penalize and suspend players for illegal checks to the heads, as well as checks to unsuspecting players. Studies show that ice hockey causes 44.3% of all sports-related traumatic brain injuries among Canadian children.
Some teams in the Switzerland National League are testing out systems that combine helmet-integrated sensors and analysis software to reveal a player's ongoing brain injury risk during a game. These sensors provide players and coaches with real-time data on head impact strength, frequency, and severity. Furthermore, if the app determines that a particular impact has the potential to cause brain injury, it will alert the coach who can in turn seek medical attention for the individual.
One of the most important strategies for a team is their forecheck. Forechecking is the act of attacking the opposition in their defensive zone. Forechecking is an important part of the dump and chase strategy (i.e. shooting the puck into the offensive zone and then chasing after it). Each team uses their own unique system but the main ones are: 2–1–2, 1–2–2, and 1–4. The 2–1–2 is the most basic forecheck system where two forwards go in deep and pressure the opposition's defencemen, the third forward stays high and the two defencemen stay at the blueline. The 1–2–2 is a bit more conservative system where one forward pressures the puck carrier and the other two forwards cover the oppositions' wingers, with the two defencemen staying at the blueline. The 1–4 is the most defensive forecheck system, referred to as the neutral zone trap, where one forward applies pressure to the puck carrier around the oppositions' blueline and the other four players stand basically in a line by their blueline in hopes the opposition will skate into one of them. Another strategy is the left wing lock, which has two forwards pressure the puck and the left wing and the two defencemen stay at the blueline.
A team that is losing by one or two goals in the last few minutes of play will often elect to pull the goalie; that is, remove the goaltender and replace him or her with an extra attacker on the ice in the hope of gaining enough advantage to score a goal. This is a desperate act, as it sometimes leads to the opposing team extending their lead by scoring a goal in the empty net.
There are many other little tactics used in the game of hockey. Cycling moves the puck along the boards in the offensive zone to create a scoring chance by making defenders tired or moving them out of position. Pinching is when a defenceman pressures the opposition's winger in the offensive zone when they are breaking out, attempting to stop their attack and keep the puck in the offensive zone. A saucer pass is a pass used when an opposition's stick or body is in the passing lane. It is the act of raising the puck over the obstruction and having it land on a teammate's stick.
A deke, short for "decoy", is a feint with the body or stick to fool a defender or the goalie. Many modern players, such as Pavel Datsyuk, Sidney Crosby and Patrick Kane, have picked up the skill of "dangling", which is fancier deking and requires more stick handling skills.
A tactic used by a player to keep possession of the puck is stick handling and also known as ragging. A player can use their stick to manipulate the puck out of reach of opposing players, while attempting to skate past them. When combined with deking or dangling skills, a player can attempt an end-to-end rush and make a solo play to score. Ragging is also a common penalty-killing tactic to use up time during a penalty's duration.
The earliest available records of women's ice hockey were in the late 19th-century in Canada. Much like the men's game, women had previously been playing a conglomeration of stick-and-ball ice games. As with men's hockey, the women's game developed at first without an organizing body. A tournament in 1902 between Montreal and Trois-Rivières was billed as the first women's ice hockey championship tournament. Several tournaments, such as at the Banff Winter Carnival, were held in the early 20th century with numerous women's teams such as the Seattle Vamps and Vancouver Amazons. Organizations started to develop in the 1920s, such as the Ladies Ontario Hockey Association in Canada, and later, the Dominion Women's Amateur Hockey Association.
Starting in Canada in 1961, the women's game spread to more universities after the Fitness and Amateur Sport Act came into force in whereby the Government of Canada made an official commitment to "encourage, promote and develop fitness and amateur sport in Canada.""Sport Canada and the Public Policy Framework for Participation and Excellence in Sport"
Today, the women's game is played from youth through adult leagues, and at the university level in North America and internationally. In 2019, the Professional Women's Hockey Players Association was formed by over 150 players with the goal of creating a sustainable professional league for women's ice hockey in North America. Today, there are major professional women's hockey leagues: the Professional Women's Hockey League, with teams in the United States and Canada, and the Zhenskaya Hockey League, with teams in Russia and, previously, China.
Prior to the professionalization of women's ice hockey in the 21st century, professional women hockey players who played against men tended to be goaltenders. The United States Hockey League (USHL) welcomed the first female professional ice hockey player in 1969–70, when the Marquette Iron Rangers signed 18-year-old goaltender Karen Koch. Only one woman has ever played in the National Hockey League (NHL), goaltender Manon Rhéaume. Rhéaume played in NHL pre-season games as a goaltender for the Tampa Bay Lightning against the St. Louis Blues and the Boston Bruins. In 2003, forward Hayley Wickenheiser played with the Kirkkonummi HC Salamat in the Finnish men's Suomi-sarja league. Women have occasionally competed in North American minor leagues: among them Rhéaume, and fellow goaltenders Kelly Dyer and Erin Whitten. Defenceman Angela Ruggiero became the first woman to actively play in a regular season professional hockey game in North America at a position other than goalie, playing in a single game for the Tulsa Oilers of the Central Hockey League.
Between 1995 and 2005 the number of women's hockey participants increased by 400 percent. In 2011, Canada had 85,827 women players, the United States had 65,609, Finland 4,760, Sweden 3,075 and Switzerland 1,172.
Women's ice hockey was added as an Olympic medal sport eight years after the first official women's ice hockey world championship in 1990, at the 1998 Winter Olympics in Nagano, Japan.
As of 2025, more than forty national teams participate in the annual competition, across four divisions: ten teams play in the top division and twelve teams each in Division I, Division II, and Division III. From the introduction of women's ice hockey as a medal sport in 1998, the top division tournament was not held in Olympic years until a change was approved to the IIHF Statutes & Bylaws in 2021; the 2022 top division tournament was the first to be held in an Olympic season.
Prior to this point, body checking had been a part of the women's game in most cases, including in Europe. It was not until after the 1990 Women's World Championship that body checking was eliminated from women's hockey internationally. In addition, until the mid-2000s, obstruction and interference were allowed, including pushing players in front of the net, minor hooking, and setting picks. When the National Hockey League removed obstruction and interference in the mid-2000s, minor hockey leagues and female leagues followed suit. In women's IIHF ice hockey today, body checking is considered an "illegal hit" and is punishable by a minor penalty, major penalty and game misconduct, or match penalty.
The idea of reintroducing body checking to the female game after its removal in the 1980s and 1990s remains controversial. Some of those opposed to its reintroduction maintain it would lead to a loss of female participants, as once stated by Arto Sieppi, Finland's director of women's hockey. Sieppi made the statement in response to claims made by the head coach of Sweden's national women's team, Peter Elander, who had claimed its absence was due to patriarchal sexism.
The Svenska damhockeyligan (SDHL), known as the Swedish Women's Hockey League in English, announced in 2022 that it would include body checking during its 2022–23 season, but would maintain a prohibition on open-ice hits. The new program also applies to the Damettan, Sweden's second-tier women's league. The Professional Women's Hockey League, the highest level of women's professional hockey, which debuted in 2024, also allows body checking. The PWHL rule-book outlines that body checking is permissible "when there is a clear intention of playing the puck or attempting to 'gain possession' of the puck", which is allowed principally along the boards. League executive Jayna Hefford has stated that body checking was included at the behest of players, and the league's physicality drew positive reviews when the league began play in January 2024.
The American Hockey League (AHL) is the primary developmental professional league for players aspiring to enter the NHL. It comprises 31 teams from the United States and Canada. It is run as a Farm team to the NHL, with the vast majority of AHL players under contract to an NHL team. The ECHL (called the East Coast Hockey League before the 2003–04 season) is a mid-level minor league in the United States with a few players under contract to NHL or AHL teams.
As of 2019, there are three minor professional leagues with no NHL affiliations: the Federal Prospects Hockey League (FPHL), (LNAH), and the Southern Professional Hockey League (SPHL).
U Sports ice hockey is the highest level of play at the Canadian university level under the auspices of U Sports, Canada's governing body for university sports. As these players compete at the university level, they are obligated to follow the rule of standard eligibility of five years. In the United States especially, college hockey is popular and the best university teams compete in the annual NCAA Men's Ice Hockey Championship. The American Collegiate Hockey Association is composed of college teams at the club level.
In Canada, the Canadian Hockey League is an umbrella organization comprising three major junior leagues: the Ontario Hockey League, the Western Hockey League, and the Quebec Maritimes Junior Hockey League. It attracts players from Canada, the United States, and Europe. The major junior players are considered amateurs as they are under 21-years-old and not paid a salary, rather a stipend, and play a schedule similar to a professional league. Typically, the many players directly from the major junior leagues. In the United States, the United States Hockey League (USHL) is the highest junior league. Players in this league are also amateur with players required to be under 21-years old, but do not get a stipend, which allows players to retain their eligibility for participation in NCAA ice hockey.
The Professional Women's Hockey League is the highest level of club competition in women's hockey. It was founded in 2023 and debuted in 2024 with three teams in Canada and three in the United States.
The second division of hockey in Eurasia is the Supreme Hockey League (VHL). This league features 24 teams from Russia and 2 from Kazakhstan. This league is currently being converted to a farm league for the KHL, similarly to the AHL's function in relation to the NHL. The third division is the Russian Hockey League, which features only teams from Russia. The Asia League, an international ice hockey league featuring clubs from China, Japan, South Korea, and the Russian Far East, is the successor to the Japan Ice Hockey League.
The highest junior league in Eurasia is the Junior Hockey League (MHL). It features 32 teams from post-Soviet states, predominantly Russia. The second tier to this league is the Junior Hockey League Championships (MHL-B).
Beginning in the 2014–15 season, the Champions Hockey League was launched, a league consisting of first-tier teams from several European countries, running parallel to the teams' domestic leagues. The competition is meant to serve as a Europe-wide ice hockey club championship. The competition is a direct successor to the European Trophy and is related to the 2008–09 tournament of the same name.
There are also several annual tournaments for clubs, held outside of league play. Pre-season tournaments include the European Trophy, Tampere Cup and the Pajulahti Cup. One of the oldest international ice hockey competition for clubs is the Spengler Cup, held every year in Davos, Switzerland, between Christmas and New Year's Day. It was first awarded in 1923 to the Oxford University Ice Hockey Club. The Memorial Cup, a competition for junior-level (age 20 and under) clubs is held annually from a pool of junior championship teams in Canada and the United States.
International club competitions organized by the IIHF include the Continental Cup, the Victoria Cup and the European Women's Champions Cup. The World Junior Club Cup is an annual tournament of junior ice hockey clubs representing each of the top junior leagues.
Ice hockey in Africa is a small but growing sport; while no African ice hockey playing nation has a domestic national league, there are several regional leagues in South Africa.
National teams representing the member federations of the IIHF compete annually in the IIHF Ice Hockey World Championships. Teams are selected from the available players by the individual federations, without restriction on amateur or professional status. Since it is held in the spring, the tournament coincides with the annual NHL Stanley Cup playoffs and many of the top players are hence not available to participate in the tournament. Many of the NHL players who do play in the IIHF tournament come from teams eliminated before the playoffs or in the first round, and federations often hold open spots until the tournament to allow for players to join the tournament after their club team is eliminated. For many years, the tournament was an amateur-only tournament, but this restriction was removed, beginning in 1977.
The Summit Series and 1974 Summit Series, two series pitting the best Canadian and Soviet players without IIHF restrictions were major successes, and established a rivalry between Canada and the USSR. In the spirit of best-versus-best without restrictions on amateur or professional status, the series were followed by five Canada Cup tournaments, played in North America. Two NHL versus USSR series were also held: the 1979 Challenge Cup and Rendez-vous '87. The Canada Cup tournament later became the World Cup of Hockey, played in 1996, 2004 and 2016. The United States won in 1996 and Canada won in 2004 and 2016.
Since the initial women's world championships in 1990, there have been fifteen tournaments. Women's hockey has been played at the Olympics since 1998. The only finals in the women's world championship or Olympics that did not involve both Canada and the United States were the 2006 Winter Olympic final between Canada and Sweden and 2019 World Championship final between the US and Finland.
Other ice hockey tournaments featuring national teams include the World Junior Championship, the World U18 Championships, the World U-17 Hockey Challenge, the World Junior A Challenge, the Ivan Hlinka Memorial Tournament, the World Women's U18 Championships and the 4 Nations Cup. The annual Euro Hockey Tour, an unofficial European championship between the national men's teams of the Czech Republic, Finland, Russia and Sweden have been played since 1996–97.
The record was approached but not broken at the 2014 NHL Winter Classic, which also held at Michigan Stadium, with the Detroit Red Wings as the home team and the Toronto Maple Leafs as the opposing team with an announced crowd of 105,491. The record for an NHL Stanley Cup playoff game is 28,183, set on April 23, 1996, at the Thunderdome during a Tampa Bay Lightning – Philadelphia Flyers game.
The attendance record for a professional women's game was set on April 20, 2024, when a sold-out crowd of 21,105 people at the Bell Centre in Montreal watched a PWHL game between PWHL Montreal and PWHL Toronto.
In addition, ice hockey is the most popular winter sport in Austria, Belarus, the Czech Republic, Finland, Germany, Latvia, Norway, Russia, Slovakia, Sweden, and Switzerland. North America's National Hockey League (NHL) is the highest level for men's ice hockey and the strongest professional ice hockey league in the world. The Kontinental Hockey League (KHL) is the highest league in Russia and much of Eastern Europe.
The International Ice Hockey Federation (IIHF) is the formal governing body for international ice hockey, with the IIHF managing international tournaments and maintaining the IIHF World Ranking. Worldwide, the International Ice Hockey Federation has 83 member national associations, comprising 60 full members, 22 associate members, and one affiliate member.
In international competitions, the national teams of six countries (the Big Six) predominate: Canada, Czechia, Finland, Russia, Sweden, and the United States. Of the 69 medals awarded all-time in men's competition at the Olympics, only seven medals were not awarded to one of those countries (or two of their precursors: the Soviet Union for Russia, and Czechoslovakia for Czechia). In the annual Ice Hockey World Championships, 177 of 201 medals have been awarded to the six nations; Canada has won the most gold medals. Teams outside the Big Six have won only nine medals in either competition since 1953.Including former incarnations of them, such as Czechoslovakia or the Soviet Union.
The World Cup of Hockey is organized by the National Hockey League and the National Hockey League Players' Association (NHLPA), unlike the annual World Championships and quadrennial Olympic tournament, both run by the International Ice Hockey Federation. World Cup games are played under NHL rules and not those of the IIHF, and the tournament occurs prior to the NHL pre-season, allowing for all NHL players to be available, unlike the World Championships, which overlaps with the NHL's Stanley Cup playoffs. Furthermore, all twelve Women's Olympic and 36 IIHF Women's World Championship medals were awarded to one of the Big Six. The Canadian national team or the United States national team have between them won every gold medal of either series.
