2021 Intercontinental GT Challenge

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.

Calendar
At the annual press conference during the 2020 24 Hours of Spa on 23 October, the Stéphane Ratel Organisation announced the first draft of the 2021 calendar.

Kyalami 9 Hours was rescheduled from 2–4 December 2021 to 3–5 February 2022 due to SARS-CoV-2 Omicron variant cases in South Africa.
