2008 AMA National Speedway Championship

The 2008 AMA National Speedway Championship Series was staged over three rounds, which were held at Costa Mesa (June 7), Auburn (July 25) and Auburn (September 20). Defending champion Billy Hamill only raced in the opening round. In his absence, Billy Janniro won the title for the first time, winning all three rounds in the process. It was the first time neither Greg Hancock or Billy Hamill had won the title since Mike Faria in 1997.
