The 2009 24 Hours of Le Mans was the 77th Grand Prix of Endurance, an endurance auto race run over 24 hours. It took place at the Circuit de la Sarthe, Le Mans, France, and was organised by the Automobile Club de l'Ouest (ACO) over 13–14 June 2009 and was started by Fiat and Ferrari chairman Luca Cordero di Montezemolo at 15:00 local time (13:00 UTC). A test day was initially scheduled for 31 May that year, but was canceled by the ACO due to economic concerns. The race was attended by 234,800 spectators.
