Ice hockey in Seattle

Ice hockey in Seattle includes professional teams as early as 1915, including the Seattle Metropolitans, the first United States-based team to win the Stanley Cup. Presently the city has a National Hockey League franchise, the Seattle Kraken, who began play in the 2021–22 season.

Historical teams
Professional ice hockey in Seattle dates back to the formation of the Pacific Coast Hockey Association (PCHA)'s Seattle Metropolitans in 1915. The 1917 Metropolitans were the first United States-based team to win the Stanley Cup, but folded in 1924. The Seattle Totems played in the minor Western Hockey League (WHL) from 1944 until the WHL's dissolution in 1975.

Failed attempts at expansion
On June 12, 1974, the NHL announced that a Seattle group headed by Vince Abbey of the Totems had been awarded a tentative expansion team to begin play in the 1976–77 season along with a team in Denver. The team, which according to season ticket promotions would have kept the WHL name of Totems, never came to fruition because of the original WHL's instability (the WHL was shut down the day the potential NHL team was announced), the inability of Abbey to gather the necessary funding and meet deadlines, and the poor performances on the ice and at the box office of 1974 expansion teams the Washington Capitals and the Kansas City Scouts. Abbey later came up short in bid to purchase the Pittsburgh Penguins and move the team to Seattle when they were sold in a bankruptcy auction for US$4.4 million in June 1975. The NHL quickly rescinded the expansion offer and Abbey filed a lawsuit against the NHL, which he lost, and ended up paying the Vancouver Canucks over US$600,000 in damages.

A second attempt at an NHL expansion team in Seattle by a local group was made in 1990, but it failed again over the financial terms the NHL demanded. Then-Seattle SuperSonics owner Barry Ackerley committed to submitting an expansion application to the NHL by a September 15, 1990, deadline as part of a proposed new arena deal, provided that a group could be found willing to meet the NHL's asking price of $50 million. His son Bill, President of the Ackerley Group, worked with Bill Lear of the First National Bank of Chicago, in order to find an ownership group for the prospective franchise. The only group to step forward was led by Microsoft executive Chris Larson and former Seattle Totems player then coach Bill MacFarland. Ackerley and the Larson/MacFarland group met multiple times, but the Larson/MacFarland group determined that the expansion franchise was worth $15 million less than what the NHL was asking for. Ackerley advised that the only application they would be a party to was one that met the NHL's $50 million threshold. As a result, when Bill Ackerley and Bill Lear met with the NHL's Board of Governors on December 5, 1990, they advised the group that they (Ackerley) were unsuccessful in finding an ownership group that was willing to meet the NHL's asking price, and so they were, out of respect to the Board of Governor's and their process, withdrawing their application. However, they also advised the Board that there was a Seattle Group, Larson/MacFarland, that wanted to present their offer to the Board, but the Ackerley group was not to be a party to that effort. As a result, the Seattle bid was denied as the NHL was able to find two markets (Ottawa and Tampa Bay) willing to meet their price. Larson and MacFarland represented to the Seattle media that it was the Ackerley Group that cost Seattle a chance at an NHL team, but in fact it was Larson and MacFarland's unwillingness to meet the NHL's expansion price. A US$50 million expansion fee was more than any NHL club was valued at the time; a US$5 million down payment that would be forfeited if 10,000 season tickets weren't sold in the first year — the SuperSonics had never sold more than 9,000 season tickets; season tickets needed to produce at least US$9 million annually, which would've made the tickets the second most expensive for a team in the area at the time; a 20-year lease with a "substantial" share of arena revenues from concessions, parking, and ad signage; priority status for postseason arena dates; and a secured US$5 million line of credit in case the league had to take over ownership of the team at any point was also required. As a result of these factors, Seattle was unable to secure an NHL franchise as part of its efforts to build a new arena.

Later talks about a NHL team for Seattle were derailed by KeyArena. While originally built with an acceptable ice hockey configuration that was used by the WHL Totems, the largest arena in the Seattle area was considered problematic for NHL hockey from 1995 to 2018 due to renovations taking place in 1994 and 1995 that were tailored to the arena's major tenant at the time, the NBA's Seattle SuperSonics. Notably, the sight lines for ice hockey left much to be desired. The scoreboard was significantly off-center in the arena's new ice hockey configuration, and so many lower-bowl seats were obstructed that half the lower bowl had to be curtained off for ice hockey, a layout that also troubled the Phoenix Coyotes during their tenancy at the basketball-centric America West Arena. This was a major factor in the major junior Seattle Thunderbirds leaving for their own building in Kent in 2009. In 2012, League deputy commissioner Bill Daly stated that KeyArena would be "a difficult arena for hockey" due to the large number of obstructed-view seats. All NHL exhibition games held in Seattle after the renovation were instead hosted at the Tacoma Dome 30 miles south of Seattle due to the issues KeyArena presented with its altered ice hockey configuration.

Expansion and relocation proposals often came with a new arena proposal, especially after the SuperSonics relocated to Oklahoma City in 2008. From 2012 on as the NHL's interest in Seattle as a market rose, the city was positioned as a locale for expansion or a relocating team pending a viable arena. Multiple reports suggested Chicago Wolves owner and businessman Don Levin had expressed interest in building a new arena in nearby Bellevue that could host an NHL team. On February 16, 2012, a plan was announced to build a new arena in Seattle's SoDo district, just south of Safeco Field. An investment group, headed by hedge-fund manager Chris Hansen, proposed the arena seeking a return of the SuperSonics and was interested in possibly having an NHL team as well. When Greg Jamison was unable to meet a deadline to purchase the Phoenix Coyotes on January 31, 2013, speculation began that the team would be relocated to Seattle. On June 16, 2013, it was confirmed that the Phoenix Coyotes would be moving to Seattle if an arena deal between the team and the City of Glendale was not reached. Ray Bartozek and Anthony Lanza would purchase the franchise for US$220 million and immediately begin operations in Seattle for the following season. However, on July 3, 2013, the Glendale City Council narrowly voted 4–3 to keep the Phoenix Coyotes in Glendale. A 2013 study by Nate Silver concluded that Seattle had the largest number of avid ice hockey fans of any U.S. media market that did not have an NHL team.

Successful expansion
On December 4, 2017, the Seattle City Council voted 7–1 to approve a memorandum of understanding between the city of Seattle and the Los Angeles-based Oak View Group, co-founded by Tim Leiweke, for renovations of KeyArena. Renovations for the arena began in 2018 and were completed in 2020, at which point the arena was renamed Climate Pledge Arena. The current roof will remain in place, as it is considered a landmark. The rest of the building will see a complete renovation with land being dug down and out. While the renovations are intended for acquiring an NHL franchise, acquiring a new SuperSonics basketball team was also within the design of the approval. On December 7, the NHL's board of governors agreed to consider an expansion application from Seattle, with an expansion fee set at US$650 million. The Seattle ownership group was represented by David Bonderman and Jerry Bruckheimer, who conducted a preliminary season ticket drive to gauge interest in Seattle.

On February 13, 2018, the Oak View Group filed an application with the NHL for an expansion team and paid a US$10 million application fee. At the time, the earliest a Seattle NHL expansion team could have begun playing was the 2020–21 season pending the completion of arena renovations.

On March 1, 2018, a ticket drive began to gauge interests in season ticket deposits. Oak View reported that their initial goal of 10,000 deposits was surpassed in 12 minutes, and that they received 25,000 deposits in 75 minutes. On April 11, 2018, Tod Leiweke was named CEO of Seattle's NHL expansion team. On June 18, 2018, Dave Tippett was named as a senior advisor. Another step towards an expansion team was taken on October 2, 2018, when the NHL Executive Committee unanimously agreed to recommend the expansion bid to a vote of the Board of Governors in December.

The NHL Board of Governors voted unanimously to approve Seattle's expansion team on December 4, 2018. Seattle will begin play in the 2021–22 season as a member of the Pacific Division in the Western Conference; therefore the Arizona Coyotes will shift from the Pacific Division to the Central Division to balance out the four divisions at eight teams each. In May 2019, the team launched an interactive "fan portal" where fans can weigh in on the team name and uniform colors, answer poll questions, get information about ticket pricing and seating, and view a timeline of past and future key events involving the club and a section that spotlights some of the season-ticket depositors.

On July 23, 2020, the franchise announced their team name, the Seattle Kraken, as well as their team colors, branding, and home jersey. The event was held under the banner of "Release the Kraken", a phrase popularized by the 1981 film Clash of the Titans and the 2010 remake. "Kraken" was a name that was already popular with fans prior to its official adoption. The franchise's promotional materials state that it was adopted to honor the maritime culture of Seattle, as well as in reference to the giant Pacific octopus, the largest species of octopus in the world, which can be found in the waters of the Pacific Northwest.

On April 30, 2021, the franchise paid the final installment of the $650 million expansion fee, officially making the Seattle Kraken the 32nd team of the NHL.

An expansion draft for the Kraken was held on July 21, 2021, in a similar manner to a previous expansion draft held in 2017 for the Vegas Golden Knights, who were exempt from it.

Junior hockey
In the Puget Sound region, two teams participate in the Canadian major junior leagues: the Seattle Thunderbirds, based 20 mi south of Seattle in Kent, and Everett Silvertips, 25 mi north of Seattle in Everett. Both play in the Western Hockey League.

The Seattle Jr. Totems compete in the Western States Hockey League and play their home games at Olympic View Arena in Mountlake Terrace, Washington, 13 mi north of Seattle.
