Formula One (F1) is the Fédération Internationale de l'Automobile's (FIA) highest class of open-wheeled auto racing, named for the strict rules ("formula") governing its participants and vehicles. A Formula One World Championship season comprises numerous global races, known as Grands Prix, held over three days with practice, qualifying, and a main Sunday race, all contributing to annual championships for both drivers and constructors. Historically, race lengths have evolved, with current standard Grands Prix covering 305 km (excluding the shorter Monaco Grand Prix) and having a maximum duration of three hours, including stoppages, since 2021.

The championship began with the 1950 British Grand Prix, and iconic events like the British and Italian Grands Prix have each been held 76 times, with Italy's Monza Circuit hosting the most races overall (75). As of 2025, F1 has staged over 1,149 World Championship events across 76 seasons in 34 countries and at 77 racing circuits, establishing itself as a premier global motorsport spectacle.
