The 1957 Formula One season was the 11th season of FIA Formula One motor racing. It featured the 1957 World Championship of Drivers, which commenced on 13 January 1957 and ended on 8 September after eight races. Juan Manuel Fangio won his fourth consecutive title, his fifth in total, in his final championship. A feat that would not be beaten until Michael Schumacher in 2003. The season also included numerous non-championship races for Formula One cars. Until the 2006 season, this was the last season during which all championship Grand Prix races were won by cars powered by an engine built by the same constructor that also built chassis.

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.
