The 2008 Adelaide Sevens, promoted as the International Rugby Sevens Adelaide 2008, was a rugby sevens tournament that was part of the IRB Sevens World Series in the 2007–08 season. It was the Australian Sevens leg of the series, held on the weekend of 5 and 6 April at the Adelaide Oval in South Australia.
