The Adelaide 36ers are an Australian professional men's basketball team in the National Basketball League (NBL). The 36ers are the only team in the league representing the state of South Australia and are based in the state's capital of Adelaide. The club was originally called the Adelaide City Eagles when they joined the NBL in 1982, but changed their name to the 36ers the following year. The 36ers nickname comes from the fact that the Colony of South Australia was officially proclaimed on 28 December 1836. Since 2019, the 36ers play their home games at the Adelaide Entertainment Centre.
