The 2008 United States motorcycle Grand Prix was the eleventh round of the 2008 MotoGP championship. It took place on the weekend of July 18–20, 2008, at the Laguna Seca circuit. It was an eventful race between Valentino Rossi and Casey Stoner where the lead was hotly contested between the two. On lap 23, with Rossi leading after an ingenious but controversial pass down the corkscrew, Stoner entered into the last corner too deep and ended up in the gravel trap. Rossi retained his lead for the remainder of the race while Stoner managed to finish in second place despite his mistake.
