The 2010 Le Mans Series season was the seventh season of Automobile Club de l'Ouest's Le Mans Series. It featured five events between 11 April and 12 September 2010. For the first time in 2010, Formula Le Mans (FLM) cars were run in a fifth class in the series, running alongside Le Mans Prototype cars and GT cars, rather than as a support series. It was also the final season when GT1 cars were allowed to run in the series.
Stéphane Sarrazin won the LMP1 championship despite sharing his car with Nicolas Lapierre for most of the season; Sarrazin did not run with his usual Team Oreca Matmut outfit at the 1000 km of Spa, instead gaining championship points with his Peugeot Sport teammates in a precursor to the 24 Hours of Le Mans the following month. Despite this, Sarrazin won only one race, winning at the 1000 km of Algarve with Lapierre and Olivier Panis. Lapierre was second ahead of Rinaldo Capello, who won at Paul Ricard with Allan McNish. Other class victories went to Sébastien Bourdais, Pedro Lamy and Simon Pagenaud at Spa, Greg Mansell and Leo Mansell at the Hungaroring, and Nicolas Minassian and Anthony Davidson at Silverstone. In LMP2, Thomas Erdos and Mike Newton claimed the championship for the second time, after their more consistent finishes helped them to fend off Strakka Racing's Jonny Kane, Danny Watts and Nick Leventis, who won three races to one for Erdos and Newton. The only other win was taken by Miguel Amaral and Olivier Pla at Spa.
