2023 European Le Mans Series

The 2023 European Le Mans Series was the twentieth season of the Automobile Club de l'Ouest's (ACO) European Le Mans Series. The six-event season began at Circuit de Barcelona-Catalunya on 23 April and finished at Algarve International Circuit on 22 October.

The series was open to Le Mans Prototypes, divided into the LMP2 and LMP3 classes, and grand tourer-style racing cars in the LMGTE class. The season was the last for the LMGTE class.

Calendar
The provisional calendar for the 2023 season was announced on 22 September 2022. MotorLand Aragón was added to the calendar for the first time, replacing the round at Monza, which left after serving as a late replacement for the Hungaroring during the 2022 season. The Portimão round was later postponed one week to alleviate a clash with the 2023 Petit Le Mans.

On 11 April it was announced the 4 Hours of Imola would be postponed due to ongoing works on the pit lane and paddock areas. On 14 April, the 4 Hours of Imola were officially cancelled, with the Portimão round becoming a double-header to fill the void.

LMP2
All cars in the LMP2 class used the Gibson GK428 V8 engine and Goodyear tyres. Entries in the LMP2 Pro-Am class, set aside for teams with a Bronze-rated driver in their line-up, are denoted with icons.

LMP3
All cars in the LMP3 class used the Nissan VK56DE 5.6L V8 engine and Michelin tyres.
