The 1953 Formula One season was the seventh season of the FIA's Formula One racing. It consisted only of several non-championship motor races. As in 1952, all races counting towards the World Championship of Drivers, apart from the Indianapolis 500, were held for cars complying with Formula Two regulations rather than with Formula One, with the Indianapolis 500 held to AAA regulations.

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.
