The 2025 Le Mans Cup, known as the 2025 Michelin Le Mans Cup for sponsorship reasons, was the tenth season of the Le Mans Cup. The six-event series began at Circuit de Barcelona-Catalunya on 5 April and concluded at Algarve International Circuit on 18 October. The series was open to Le Mans Prototypes in the LMP3 class, now split into two, and grand tourer sports cars in the GT3 class. The season marked the debut of the new, third-generation LMP3 cars.

The provisional calendar for the 2025 season was announced on 2 October 2024. Silverstone Circuit was added to the calendar for the first time, replacing the round at Mugello. Starting this season, the race duration was extended from 1 hour and 50 minutes to 2 hours, except for the Silverstone round, which kept its original length. The Road to Le Mans races ran for 1 hour instead of 55 minutes.

All cars in the LMP3 class use the Toyota V35A-FTS 3.5 L twin-turbo V6 engine and Michelin tyres. Entries in the LMP3 Pro-Am class, set aside for teams with a Bronze-rated driver in their line-up, are denoted with icons.
