The Utah Mammoth are a professional ice hockey team based in Salt Lake City. The Mammoth compete in the National Hockey League (NHL) as a member of the Central Division in the Western Conference. The franchise joined the league as an expansion team for the 2024–25 season. The team plays its home games at the Delta Center, an arena they share with the Utah Jazz of the National Basketball Association (NBA).
The team was created on April 18, 2024, with the NHL Board of Governors granting an expansion franchise to Jazz owner Ryan Smith. In lieu of an expansion draft to stock the new team, Smith acquired the hockey assets (players, coaching staff, and draft picks) of the Arizona Coyotes, which suspended hockey operations at the same time. The team played its inaugural season in 2024–25 with the temporary name Utah Hockey Club while a permanent name could be determined. The team's name, colors, and jerseys for their inaugural season were revealed on June 13, 2024. After playing a full season under the temporary name, a fan vote led to the permanent naming of Utah Mammoth, which was revealed on May 7, 2025.
After just one season out of ice hockey, Salt Lake City received another IHL franchise in 1995, as the reigning Turner Cup champion Denver Grizzlies, having been replaced by the newly relocated Colorado Avalanche of the NHL, relocated to the Delta Center for the 1995–96 season as the Utah Grizzlies. The Grizzlies spent two seasons in Salt Lake City proper, including a second consecutive Turner Cup championship in 1996; notably, the Cup-clinching game 4 of the Turner Cup Finals saw an attendance of 17,381, at the time the largest single-game attendance in minor-league ice hockey history. The Grizzlies later moved to the newly constructed Maverik Center (since renamed the Maverik Center) in the suburb of West Valley City for the 1997–98 IHL season, and joined the American Hockey League (AHL) in 2001 alongside five other surviving IHL franchises upon the latter's collapse. However, the Grizzlies voluntarily suspended operations for the 2005–06 season, before being sold to Dan Gilbert, the owner of the NBA's Cleveland Cavaliers, and relocating to Cleveland, as the Lake Erie Monsters (later Cleveland Monsters) for the 2007–08 season.
The AHL iteration of the Grizzlies were subsequently replaced by a relocated ECHL franchise Utah Grizzlies; the franchise had most recently played in Lexington, Kentucky, as the Lexington Men O' War but had become dormant after the 2002–03 ECHL season. The new Grizzlies began play out of the E Center in 2005, immediately after their AHL predecessor had gone dormant, and have played 19 seasons in the ECHL since. However, the franchise has been comparatively unsuccessful; although they have missed the playoffs only four times, they have won just one division championship and no conference championships, only having reached the conference finals twice. In September 2025, over a year after the Mammoth's arrival, the Grizzlies were sold to an ownership group based in Trenton, New Jersey; the 2025–26 season will be the franchise's last in Utah before moving to Trenton.
Delta Center previously hosted multiple Los Angeles Kings preseason games as part of the NHL's Frozen Fury series. However, the arena was not considered well suited to host ice hockey permanently, owing to poor sightlines and broadcasting capabilities. Maverik Center and Peaks Ice Arena in the suburb of Provo, hosted the ice hockey tournaments at the 2002 Winter Olympics in Salt Lake City, which featured NHL players. Salt Lake City is also the host city for the 2034 Winter Olympics.
On April 13, 2024, it was reported that, with the NHL's permission, the Coyotes were making efforts to relocate to Salt Lake City following concerns about an indefinite timeframe on a new arena and the effects of continued play at the 4,600-seat Mullett Arena. The deal became official on April 18 after the NHL Board of Governors granted an expansion franchise to Utah using the Coyotes' hockey assets. Under the terms of the agreement, the Coyotes franchise was essentially split in half. The Coyotes franchise will be considered "inactive", with Utah regarded as an expansion team rather than a successor to the Coyotes in a similar situation to the Cleveland Browns and Baltimore Ravens of the National Football League.
While the deal was reported in the media as a $1.2 billion "sale" of the Coyotes, it is in reality two separate transactions in which $1 billion is being paid by the NHL to Alex Meruelo for the Coyotes franchise while Smith is paying a $1.2 billion expansion fee to the NHL's other owners. The $200 million difference is thus in effect a de facto relocation fee to be shared equally by the other 31 NHL clubs. According to Smith, the team sold more than 11,000 season-ticket deposits in the four hours after going on sale, with 6,000 sold in the first two hours.
The team was formally introduced at the Delta Center on April 26, with over 12,000 fans attending a welcome celebration featuring players and coaches. On May 6, the Smith Entertainment Group announced that a practice facility would be built for the team in the nearby suburb of Sandy, Utah, which had its groundbreaking ceremony on August 12. On June 13, the NHL announced that the sale of the franchise had officially been completed and that the team would be known as "Utah Hockey Club" for their inaugural season.
Utah played their first preseason game on September 22, 2024, defeating the St. Louis Blues 5–3 in a neutral-site matchup played at Wells Fargo Arena in Des Moines, Iowa. On September 23, Utah played their first home preseason game at the Delta Center, defeating the Los Angeles Kings 3–2.
On October 4, Utah named forward Clayton Keller as its first captain in franchise history. On October 8, the team defeated the Chicago Blackhawks 5–2 in its first regular season contest, with Dylan Guenther scoring the first goal. The team's first season ended with a record of 38–31–13, placing them sixth in the Central Division, but ultimately out of playoff contention.
On June 13, it was announced that the team would be known as the "Utah Hockey Club" for the 2024–25 season. In January 2025, it was revealed that the "Utah Yetis" and singular "Utah Yeti" brands were refused by the U.S. Patent and Trademark Office due to its similarity to the company name Yeti Holdings. Prior to the rejection, it had been widely expected, even among Utah players, that the "Yeti" name would be chosen. On January 29, the team announced that fans attending their following four home games in late January and early February could vote for a permanent identity for the club, with the final three options being the existing Utah Hockey Club, Utah Mammoth, and Utah Wasatch. While the Wasatch name was not one of the six finalists, it was intended to honor the idea of a mythical snow creature similar to the yeti, with a "Utah-centric" approach inspired by the Wasatch Mountains. One day later, on January 30, the team announced that "Wasatch" was being removed from the survey, being replaced by previously announced finalist "Utah Outlaws". On April 30, speculation arose that "Mammoth" was the selected name following leaks online that showed the team changing its YouTube handle to @UtahMammoth. These speculations were confirmed on May 7, when the team officially revealed their permanent name as the Utah Mammoth. A new logo and uniforms were also revealed, retaining the same color scheme.
On May 7, 2025, on the day the permanent "Mammoth" name was unveiled, a new logo and uniform set were unveiled to accompany the name change. Using the same blue, black, and white color scheme, the logo features a "Mountain Mammoth" with the top of the mammoth's head showing a depiction of mountain peaks, a nod to Utah's Wasatch Mountains. One of the mountains also forms an outline resembling the borders of the state of Utah. For the home uniforms, the "UTAH" wordmark was replaced with the new primary logo. The road uniforms retained the diagonal "UTAH" wordmark, but all text on both uniforms were updated to the new "Mammoth Sans" font. The inaugural season shoulder patches were replaced on the home uniforms by a Utah state outline alternate logo, while the primary mammoth logo replaced them on the road jersey.
On October 15, 2025, the team unveiled their permanent mascot, a blue woolly mammoth named Tusky, before the team's first home game under the Mammoth name.
On September 4, Utah announced that former Coyotes play-by-play announcer Matt McConnell had been hired for the same position, with ESPN analyst Dominic Moore and Seattle Kraken color analyst Nick Olczyk serving as TV analysts.
