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 (24 Hours of Spa on 31 July), one in North America (Indianapolis 8 Hour), and one in Africa (Kyalami 9 Hours, later postponed to 5 February 2022). Nicky Catsburg and Augusto Farfus were the defending drivers' champions and Porsche was the defending Manufacturers' champion.
Championship points were awarded for the first ten positions in each race. Entries were required to complete 75% of the winning car's race distance in order to be classified and earn points. Individual drivers were required to participate for a minimum of 25 minutes in order to earn championship points in any race. A manufacturer only received points for its two highest placed cars in each round.
