The 1952 Formula One season was the sixth season of FIA Formula One motor racing. In comparison to previous seasons, the 1952 season consisted of a relatively small number of Formula One races, following the decision to run all the Grand Prix events counting towards the World Championship of Drivers to Formula Two regulations rather than Formula One. The Indianapolis 500, which also counted towards the World Championship, was still run to AAA regulations as in previous seasons. Since this season racing helmets were made mandatory in Formula One.

Formula One, commonly known as Formula 1 or F1, is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of racing since its inaugural running in 1950. The word formula in the name refers to the set of rules all participants' cars must follow. A Formula One season consists of a series of races, known as Grands Prix. Grands Prix take place in multiple countries and continents on either purpose-built circuits or closed public roads.
