The 2009 United States motorcycle Grand Prix was the eighth round of the 2009 Grand Prix motorcycle racing season. It took place on the weekend of July 3–5, 2009 at Mazda Raceway Laguna Seca. As usual, only the MotoGP class was permitted to race at Laguna Seca due to the Californian air pollution law prohibiting two-stroke engines in the state. Spain's Dani Pedrosa took his first win for a year, holding off a last-lap surge from championship leader Valentino Rossi.
