The 1950 Formula One season was the fourth season of the FIA Formula One motor racing. It featured the inaugural FIA of Drivers, which was contested over seven races between 13 May and 3 September 1950. The only one outside of Europe was the Indianapolis 500, which was run to AAA National Championship regulations. No Formula One drivers competed in the Indy 500 or vice versa. Finally, the season also included several non-championship races for Formula One cars.

Alfa Romeo entered a supercharged 158, a well-developed pre-war design that debuted in 1938, and managed to win all six races they competed in. Italian Giuseppe "Nino" Farina and Argentine teammate Juan Manuel Fangio both won three races and set three fastest laps each. But Fangio did not score points in the other three races, while Farina finished fourth in Belgium, handing him the championship.
