2015 24 Hours of Le Mans

The 83rd 24 Hours of Le Mans (French: 83^e 24 Heures du Mans) was an automobile endurance event held from 10 to 14 June 2015 at the Circuit de la Sarthe, Le Mans, France. It was the 83rd running of the 24 Hour race organised by the Automobile Club de l'Ouest as well as the third round of the 2015 FIA World Endurance Championship. A test day was held two weeks prior to the race on 31 May. A record-breaking 263,500 people attended the event.

The No. 18 Porsche 919 Hybrid of Neel Jani, Romain Dumas, and Marc Lieb started from pole position after Jani broke the circuit's lap record in qualifying. The race was won by the No. 19 Porsche of Nick Tandy and Le Mans rookies Earl Bamber and Nico Hülkenberg, followed a lap behind by the second Porsche of Mark Webber, Brendon Hartley and Timo Bernhard. Audi's best car, driven by the title defenders Benoît Tréluyer, Marcel Fässler, and André Lotterer, finished third, a further lap behind the two Porsche vehicles. This was the seventeenth overall victory for Porsche, and their first since 1998.

The LMP2 category was won by the KCMG Oreca-Nissan driven by Richard Bradley, Matthew Howson, and Nicolas Lapierre. The trio led all but nine laps of the race but only held a 48-second lead over the Jota Sport Gibson-Nissan at the race's end. Corvette Racing won their first class victory since 2011 despite one of their two cars being withdrawn after an accident in qualifying. Oliver Gavin, Tommy Milner, and Jordan Taylor held a five-lap margin in LMGTE Pro over the AF Corse Ferrari in second, after breaking away from the rest of the field in the second half of the race. The LMGTE Am class was led for most of the time by the No. 98 Aston Martin until driver Paul Dalla Lana crashed in the Ford Chicane in the final hour of the race, handing the victory to the SMP Racing Ferrari of Viktor Shaitar, Aleksey Basov, and Andrea Bertolini.
