The Catalina Casino is located in Avalon on Santa Catalina Island, off the coast of Los Angeles in California. It is the most visible landmark in Avalon Bay and when approaching the island from the mainland.
The large building contains a movie theater, ballroom, and formerly an island art and history museum. The Catalina Casino gets its name from the Italian language term casino, meaning a "gathering place". Contrary to common perception of the name, there has never been gambling at the facility.
