The 2013 FIA World Endurance Championship season was the second season of the FIA World Endurance Championship auto racing series, co-organized by the Fédération Internationale de l'Automobile (FIA) and the Automobile Club de l'Ouest (ACO). The series was open to Le Mans Prototypes and grand tourer-style racing cars meeting four ACO categories. World Championships were awarded to drivers and to LMP1 category manufacturers, and several World Cups and Endurance Trophies were awarded for the series' other categories. The eight race championship began in April at the Silverstone Circuit and ended in November at the Bahrain International Circuit. The season was marred by the death of Allan Simonsen in the 24 Hours of Le Mans.

Calendar An initial calendar was published by the FIA World Motor Sport Council on 28 September 2012. Seven of the eight races on the schedule are carried over from 2012, although several events have had their dates changed. The 6 Hours of Silverstone now begins the season in April before Spa in May and the 24 Hours of Le Mans in June. In order to save costs and utilize shipping by sea instead of air, the non-European events have all been grouped at the end of the season. São Paulo remains as the first post-European event, while the new 6 Hours of Circuit of the Americas replaces the 12 Hours of Sebring as the American round of the series. Fuji and Shanghai are moved forward on the calendar, leaving Bahrain to now close the season in November, allowing cooler temperatures than its September date in 2012.

The Silverstone race weekend was shared with the European Le Mans Series, while the Austin weekend was held in conjunction with the American Le Mans Series, although unlike the 2012 12 Hours of Sebring, both series ran separate races.

Regulation changes An additional World Cup was awarded for the 2013 season, with drivers in both LMGTE categories having a unified championship. Further, the LMP2 and LMGTE Am categories had FIA Endurance Trophies awarded for their drivers. The qualifying format of the race weekend was also changed, with teams requiring two drivers each to set two timed laps. The qualifying results were determined based on an average of the four total laps. The new qualifying format has been met with much criticism from drivers. The pre-race warm-up session has also been eliminated from the series, except in instances where extra practice may be necessary.

The LMP2 category saw several rule changes in order to lower costs, including the issuing of balance of performance updates during the course of the season. A limit was also set on the price of upgrade kits for 2012 cars for teams not purchasing 2013 chassis, while the number of engines and tyres they can utilize over the course of the season have been restricted. Diesel engines were allowed in the LMP2 category for the first time. Limits on tyres were also set in the LMGTE Am category.

Entries The World Endurance Championship received entries in four classes, including Le Mans Prototype 1 (LMP1), Le Mans Prototype 2 (LMP2), Le Mans Grand Touring Endurance — Professional (LMGTE Pro) and Le Mans Grand Touring Endurance — Amateur (LMGTE Am). The entry list for the 2013 season was released by the Automobile Club de l'Ouest on 1 February, and included six LMP1 and twelve LMP2 cars, six LMGTE Pro entries, and eight LMGTE Am cars, bringing the full grid up to thirty-two entrants. Two LMP2 teams, Starworks Motorsport and HVM Status GP later withdrew their full-season entries citing a lack of funding.
