The 2023 Formula One season held 22 Grands Prix.
The championship began with the Bahrain Grand Prix on 5 March and ended with the Abu Dhabi Grand Prix on 26 November. The calendar included races across five continents, from Australia and Japan to the United States, Brazil, and the United Arab Emirates.
The season originally included a planned 24-race calendar, but the Emilia-Romagna Grand Prix was cancelled because of severe flooding in northern Italy, and the Chinese Grand Prix remained absent after its cancellation. The final schedule therefore contained 22 races.
The 2023 calendar also introduced the Las Vegas Grand Prix, held on a Saturday night in November. Six weekends included sprint races, but those shorter events did not count as additional Grands Prix; the answer refers only to the main championship races.
