Oakland Arena, often referred to as the Oakland Coliseum Arena, is an indoor arena in Oakland, California, and part of the Oakland–Alameda County Coliseum Authority. Opened in 1966, the arena was originally home to the California Seals of the Western Hockey League (WHL), later of the National Hockey League (NHL), until their move to Cleveland in 1976. The arena most famously served as home to the Golden State Warriors of the National Basketball Association (NBA) from 1971 to 2019, excluding a period of extensive renovation during the 1996–97 NBA season.
