The 1983 FIA Formula One World Championship was the 37th season of FIA Formula One motor racing. It featured the 1983 Formula One World Championship for Drivers and the 1983 Formula One World Championship for Manufacturers, which were contested concurrently over a fifteen-race series that commenced on 13 March and ended on 15 October.

Nelson Piquet, driving for Brabham, won the Drivers' Championship, for the second time. Renault driver Alain Prost led the championship from the Belgian Grand Prix in May until the final race in South Africa, where he retired and enabled the Brazilian to snatch the title. It was the first title by a driver using a turbocharged engine and the last title by a Brabham driver. Piquet won the title despite his team only finishing third in the World Constructors Championship; he would be the last Drivers' Champion for a constructor that was placed third or lower until 2024.

Ferrari won the Constructors' Championship, despite neither of its drivers finishing in the top two positions of the Drivers' Championship with the Maranello team's highest placing driver, René Arnoux, finishing only third in the drivers' standings overall – a unique feat in Formula One history.

The season also included a non-championship Formula One race for the last time: the Race of Champions, held at Brands Hatch early April and won by defending World Champion Keke Rosberg. Brands Hatch would also host a championship round later that year under the European Grand Prix title, the first time that race title had been used as an official race title for a standalone championship event rather than being used as an honorary designation for pre-existing national Grands Prix as had been the case in previous seasons.
