The 2025 Prototype Cup Germany was the fourth and final season of the Prototype Cup Germany before becoming the Prototype Cup Europe. Organised and promoted by Creventic and German automobile club ADAC, the series was contested with Le Mans Prototype 3 cars.
The championship remained with the Nissan VK56 V8-engines and is therefore the only championship in Europe, in which the second generation LMP3 cars can be used.
