The FIA World Motor Sport Council (WMSC) has approved the 23-race 2021 Formula 1 calendar, with one venue still yet to be announced.

On the same day that there was confirmation of a new five-year agreement for the Brazilian Grand Prix to be held at Interlagos until 2025 — under the new name of the Sao Paulo Grand Prix to reflect funding coming from the city — the WMSC ratified the provisional calendar announced by F1 back in early November.

The season will start in Australia on March 21, opening with a doubleheader of races on consecutive weekends that also includes Bahrain less than four months after it last hosted a race this season. There is a yet-to-be-confirmed race to be held on April 25 — originally scheduled for Vietnam, but no longer the inaugural race in Hanoi — and a provisional Spanish Grand Prix on May 9, subject to a promoter agreement.

The United States Grand Prix remains on October 24, with Austin again paired with Mexico City a week later, before Brazil, Saudi Arabia (November 28) and Abu Dhabi (December 5) round out what will be a record 23-race season. The new race in Jeddah is marked as subject to circuit homologation.
