The European Le Mans Series is a European sports car racing endurance series inspired by the 24 Hours of Le Mans race and organized by the Automobile Club de l'Ouest (ACO). The European Le Mans Series is similar to the former American Le Mans Series (ALMS) based in the United States and Canada that was running with ACO and IMSA between 1999 and 2013. ELMS team champions and runners-up receive an automatic entry to the following year's 24 Hours of Le Mans. Originally titled the Le Mans Endurance Series before becoming simply the Le Mans Series in 2006, the series was renamed once more in 2012, reusing a name previously utilized by IMSA in 2001.

Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing, touring car racing and stock car racing. Sports car races are often, though not always, endurance races that are run over particularly long distances or large amounts of time, resulting in a larger emphasis on the reliability and efficiency of the car and its drivers as opposed to outright car performance or driver skills. The FIA World Endurance Championship is an example of one of the best known sports car racing series.
