Buffalo Memorial Auditorium, colloquially known as The Aud, was a multipurpose indoor arena in downtown Buffalo, New York. Opened on October 14, 1940, it was home to the Canisius Golden Griffins (NCAA), the Buffalo Bisons (AHL), the Buffalo Bisons (NBL), the Buffalo Braves (NBA), the Buffalo Sabres (NHL), the Toronto-Buffalo Royals (WTT), the Buffalo Stallions (MSL), the Buffalo Bandits (MILL), the Buffalo Blizzard (NPSL) and the Buffalo Stampede (RHI). It also hosted events such as college basketball, concerts, professional wrestling and boxing. The venue was closed in 1996 after the construction of the venue now known as KeyBank Center, and remained vacant until being demolished in 2009.

The Buffalo Bisons were an American Hockey League ice hockey franchise that played from 1940 to 1970 in Buffalo, New York. They replaced the original Buffalo Bisons hockey team, which left the area in 1936 after its arena collapsed. They were the second professional hockey team to play their games in the Buffalo city proper, after the short-lived Buffalo Majors of the early 1930s; the previous Bisons team had played across the border at an arena in Fort Erie, Ontario.
