Rocket Mortgage FieldHouse

The Rocket Mortgage Field House formerly the Quicken Loans Arena is a multipurpose arena in downtown Cleveland, Ohio, United States. Until August 2005, it was known as Gund Arena, named for Gordon Gund, a former owner of the Cavaliers, after he paid for the naming rights. It is home to the Cleveland Cavaliers of the National Basketball Association and the Lake Erie Monsters of the AHL. It was previously home of the now-defunct Cleveland Lumberjacks of the IHL, the Cleveland Barons of the AHL, the Cleveland Gladiators of the Arena Football League, and the Cleveland Rockers of the Women's National Basketball Association. The arena was opened with a concert by Billy Joel on October 17, 1994; the Cavaliers played the first game in the arena a few weeks later. It is owned by the Gateway Economic Development Corporation, which leases it to the Cavaliers.

On May 16, 2006, the then-inactive Utah Grizzlies franchise of the AHL announced that it would move to the Quicken Loans Arena. On January 25, 2007, the team name was announced as the Lake Erie Monsters. It began play in the 2007-2008 season.

On October 16, 2007, the Las Vegas Gladiators of the Arena Football League announced that they would move to Quicken Loans Arena.

The arena replaced the Coliseum at Richfield, which was located south of Cleveland near Akron. Part of the Gateway Project to revitalize downtown Cleveland, the arena and neighboring Progressive Field were paid for with a sin tax on alcohol and tobacco. In 2005, Cavaliers majority owner Dan Gilbert (owner of Quicken Loans) renovated the arena, installing new seats, state of the art scoreboards, video systems, sound systems, arena graphics, signage, security, locker rooms, and suite upgrades, all of which were in place for the start of the Cavaliers 2005-2006 season, except for the seats, which were replaced a few sections at a time.

The arena was announced as being renamed to the Rocket Mortgage FieldHouse in April of 2019 to coincide with major renovations to the arena. Rocket Mortgage is a subsidiary of Quicken Loans.

The arena seats 20,562 for basketball, including 2,000 in the club seats, and 92 luxury suites.

The arena underwent a multi phase renovation from 2017 to 2019.
