Formula One, abbreviated to F1, is currently the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body.[1] The "formula" in the name refers to a set of rules to which all participants and vehicles must conform.[2] The Formula One World Championship season consists of a series of races, known as Grands Prix, usually held on purpose-built circuits, and in a few cases on closed city streets.[3] The results of each race are combined to determine two annual championships, one for drivers (World Drivers' Championship), and one for constructors (World Constructors' Championship).[4]
This list is for the circuits that hosted World Championship races from 1950 until now. The terms "Formula One race" and "World Championship race" were not always synonymous throughout history – see Formula One § Distinction between Formula One and World Championship races for a detailed explanation.
