The 1958 Formula One season was the 12th season of Formula One motor racing. It featured the 9th World Championship of Drivers, the first International Cup for F1 Manufacturers and five non-championship Formula One races. The World Championship was contested over eleven races between 19 January and 19 October 1958. The Indianapolis 500 counted towards the Drivers' Championship but not the Manufacturers' Cup.

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.
