Mikko Rantanen (born 29 October 1996) is a Finnish professional ice hockey player who is a forward for the Dallas Stars of the National Hockey League (NHL). He was selected in the first round, 10th overall, by the Colorado Avalanche in the 2015 NHL entry draft and made his NHL debut that year. Rantanen won the Stanley Cup with the Avalanche in 2022. Following a brief mid-season stint with the Carolina Hurricanes in 2025, Rantanen signed an eight year deal with Dallas.
Entering the 2014–15 season as the only 17-year-old to play in his third year with TPS, Rantanen signed a two-year extension to remain with the Liiga outfit on 9 October 2014. Through using his big frame and physical play, Rantanen recorded a career-high nine goals and 28 points in 56 games, also serving as an alternate captain. He also featured for TPS junior club in the postseason recording 14 points in 7 contests to help capture the championship and was given Best Player honours for his efforts.
In his National Hockey League (NHL) draft-eligible year, Rantanen was rated as the top European skater at season's end. He was taken tenth overall by the Colorado Avalanche at the 2015 NHL entry draft on 26 June 2015.
In his AHL debut, Rantanen contributed with his first goal and assist in North America during a 5–1 victory over the Stockton Heat on 24 October 2015. He continued his scoring pace with the Rampage, leading the club in all offensive categories before he was selected to the AHL All-Star Game as the second-youngest participant in the event's modern history. After receiving a three game recall to the Avalanche, Rantanen was returned to complete the season with San Antonio, becoming just the seventh teenager to reach the 60-point mark, doing so in just 52 games. In finishing sixth in overall scoring, he earned a selection to the Second All-Star Team and shared the Dudley "Red" Garrett Memorial Award alongside Frank Vatrano as the AHL's rookie of the year.
On 11 November 2016, Rantanen scored his first NHL goal 1:03 into the second period in a game against the Winnipeg Jets. The Avalanche would go on to win 3–2 in overtime. He recorded his first NHL hat trick on 8 February 2017 in a 4–0 win over the Montreal Canadiens.
Rantanen had a breakout year during the 2017–18 season, scoring 29 goals and 55 assists for 84 points in 81 games; only linemate Nathan MacKinnon had more points for Colorado. The team qualified for the 2018 Stanley Cup playoffs as the second wild card team in the Western Conference. Rantanen had four assists as the team was eliminated by the Nashville Predators in six games.
The 2018–19 season saw Rantanen continue to play at an impressive pace, highlighted by his play during the first few months of the season. By December 2018, Rantanen had earned 50 points and was on pace to score the most points by any player since the 2004–05 lockout. Although his scoring would drop off, Rantanen finished the season with 87 points in 74 games played; a career-high. He also led the team in scoring during the team's two-round playoff run.
On 28 September 2019, Rantanen signed a six-year, $55.5 million contract extension with the Avalanche.
On 26 June 2022, the Colorado Avalanche won the Stanley Cup by defeating the Tampa Bay Lightning in six games, giving Rantanen his first Stanley Cup championship.
In the 2022–23 season, after Jari Kurri and Teemu Selänne, Mikko Rantanen became the third Finn of all time to break the 50-goal mark in the NHL regular season and the third player in Colorado Avalanche club history after Joe Sakic and Milan Hejduk.
Entering the 2024–25 season and in the final year of his contract before he was set to become an unrestricted free agent, Rantanen and the Avalanche hit an impasse when it came to contract extensions; Rantanen was reportedly seeking an annual salary in the range of $14 million, while the Avalanche were unwilling to offer more than $12.6 million a year (the salary of forward Nathan MacKinnon). The two remained far apart but Rantanen continued to excel on the team, routinely remaining a top 10 scorer in the league as the season progressed.
After the trade, the Hurricanes attempted to extend Rantanen, reportedly offering a franchise-record contract worth at least $100 million during the 4 Nations Face-Off season pause. However, with Rantanen remaining noncommittal in the days leading up to the NHL's annual trade deadline, Carolina explored trading Rantanen, rather than risk losing him in unrestricted free agency for no compensation. Trade speculation further intensified after Rantanen's play disappointed in Carolina relative to his superstar expectations, especially compared to Nečas who had played well with the Avalanche. Multiple teams inquired about Rantanen leading up to the 7 March trade deadline, with talks between the Dallas Stars and Hurricanes intensifying just after midnight on the day of the deadline, with any prospective trade contingent on Rantanen signing an extension with Dallas.
Rantanen continued his progression within the Finnish junior team in earning selection to the 2015 World Junior Championships in Toronto. Despite a disappointing seventh-place finish, Rantanen contributed with four goals in five games to earn a top-three player on team selection.
During his first North American professional season and while eligible for his final junior tournament, Rantanen was loaned by the Colorado Avalanche to Captain the Finnish junior team as they hosted the 2016 World Junior Championships. While adding a stabilising veteran presence, Rantanen played a supporting role throughout the round-robin stage before stepping up his production in the Semi-final against Sweden and scoring in the Final against Russia to help Finland claim the gold medal and cap his junior career.
