The 2021 Intercontinental GT Challenge was the sixth season of the Intercontinental GT Challenge. Normally a five round season, the races in the Pacific Rim were eliminated because of pandemic-related restrictions, reducing the season to three rounds, one in Europe, one in North America, and one in Africa. Nicky Catsburg and Augusto Farfus were the defending drivers' champions and Porsche was the defending Manufacturers' champion.
