KeyArena at Seattle Center, commonly known as KeyArena, is a multipurpose arena in Seattle, Washington. It is located north of downtown in the 74-acre entertainment complex known as Seattle Center, the site of the 1962 World's Fair, the Century 21 Exposition. It is used for entertainment purposes, such as concerts, ice shows, circuses, and professional wrestling events.

It has a seating capacity for basketball games of 17,072, ice hockey games and ice shows 15,177, end-stage concerts is 16,641, and center-stage concerts and boxing 17,459. Risers hold 7,440 on the upper level and up to 7,741 on the lower level, with luxury suites adding another 1,160 seats.

It was the home to the Seattle Thunderbirds, a junior hockey team in the Western Hockey League. The Thunderbirds hosted the Memorial Cup in the Seattle Center Coliseum pre-KeyArena remodel in 1992.

On December 5, 2017 the Seattle City Council approved a memorandum of understanding for a privately financed $600 million renovation to the arena to bring the facility up to both NHL and National Basketball Association standards. Construction could start during 2018 and be done for October 2020. The city has been rumored to be a candidate for NHL and expansion or relocated teams pending the renovations to the arena or construction of a new arena.[1]
