The 2025 Porsche Mobil 1 Supercup was the 33rd Porsche Supercup season, a GT3 production one-make stock car racing series sanctioned by Porsche Motorsports GmbH in the world. It began on 16 May at Imola Circuit, Italy and ended on 7 September at the Autodromo Nazionale di Monza, Italy, after eight races, all of which are support events for the 2025 Formula One World Championship.
2024 champion Larry ten Voorde retired from the series for 2025, with fellow Dutchman Flynt Schuring taking over the No. 12 Schumacher CLRT entry.
Points were awarded to the top fifteen classified drivers in every race, using the following system:
In order for full points to be awarded, the race winner must complete at least 50% of the scheduled race distance. Half points are awarded if the race winner completes less than 50% of the race distance. In the event of a tie at the conclusion of the championship, a count-back system is used as a tie-breaker, with a driver's/constructor's best result used to decide the standings.
Due to a major accident on the opening lap reducing the number of racing laps down to 4, the second round of the 2025 Championship in Monaco was only eligible for half points.
Rookie drivers must be 25 years of age or younger to compete in the Rookies' Championship.
Guest drivers are ineligible to score points. If a guest driver finishes in first position, the second-placed finisher will receive 25 points. The same goes for every other points scoring position. So if three guest drivers end up placed fourth, fifth and sixth, the seventh-placed finisher will receive fourteen points and so forth - until the eighteenth-placed finisher receives the final point.
