The 2012 European Le Mans Series was the ninth season of the Automobile Club de l'Ouest's European Le Mans Series (previously known as simply Le Mans Series). Championship titles were awarded in five categories, with the Le Mans Series shifting its categories following its separation from the FIA World Endurance Championship. LMP1 cars were dropped due to most teams entering the FIA World Endurance Championship while a new GTC category was created to allow single make grand tourer cars and FIA GT3s to compete in endurance races. However no GTC cars competed during the season.
Due to the numerous issues the season was reduced to just three rounds, starting in Le Castellet, France on 1 April and ended at Braselton, Georgia, United States, on 20 October.
Following the ELMS decision to no longer share races with the FIA World Endurance Championship (formerly the Intercontinental Le Mans Cup), the series required new races to replace the Spa-Francorchamps and Silverstone races which now were part of the WEC. Circuit Paul Ricard was the only event carried over from 2011 and remained the season opener.Circuit Zolder was supposed to serve as the second round of the series, but on 1 April the race was cancelled due to a lack of entrants. ELMS teams were instead invited to enter the 6 Hours of Spa WEC round. Following a small number of entries at Donington, the season's two later rounds at the Brno Circuit and Autódromo Internacional do Algarve were cancelled. In place of these two rounds, an agreement was reached with the American Le Mans Series to allow ELMS competitors to participate in the Petit Le Mans for double points, with the ELMS providing transport assistance to full-season teams.
