The 2005 United States motorcycle Grand Prix was the eighth round of the 2005 MotoGP Championship. It took place on the weekend of July 8–10, 2005 at Mazda Raceway Laguna Seca. Only the MotoGP class raced here because of the Californian law on air pollution, which forbids 2-stroke engines in the state.
This round was the first motorcycle Grand Prix hosted by the United States since 1994.
