The 1949 24 Hours of Le Mans was the 17th Grand Prix of Endurance, and took place on 25 and 26 June 1949. Luigi Chinetti won the race for a third time in the first Ferrari barchetta by driving 22.5 hours. This race also saw the death of British driver Pierre Maréchal when his Aston Martin DB2 was involved in an accident between Arnage and Maison Blanche around 1:00 a.m. Marechal had attempted to pass another car there and he hit an embankment and the hapless Briton was crushed by the overturning car.

Luigi Chinetti was an Italian-born racecar driver, who emigrated to the United States during World War II. He drove in 12 consecutive 24 Hours of Le Mans races, taking three outright wins there and taking two more at the Spa 24 Hours race. Chinetti owned the North American Racing Team, which successfully ran privateer Ferraris in sports car and Formula One races. For many years he was the exclusive American importer of Ferrari automobiles to the United States.
