The 1983 Formula 1 season was the 34th 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 Constructors, which were contested concurrently over a 15-race series. Nelson Piquet won his second Drivers' Championship, driving for Brabham, while Ferrari won the Constructors' Championship.
The 1983 Formula One season began at the Jacarepaguá circuit in Rio de Janeiro, where defending champion Keke Rosberg started on pole but Nelson Piquet won the race for Brabham-BMW.
Keke Rosberg drove his Williams-Ford to victory in a wet and chaotic Monaco Grand Prix, mastering the treacherous conditions to finish ahead of Jacques Laffite and Michele Alboreto.
Michele Alboreto secured his first Formula One victory at the Detroit street circuit, driving for the Tyrrell-Ford team and finishing ahead of Keke Rosberg and Nigel Mansell.
Alain Prost won the British Grand Prix at Silverstone in his Renault, taking the lead in the Drivers' Championship as the season reached its halfway point.
René Arnoux won the German Grand Prix at Hockenheim for Ferrari, achieving a 1-2 finish for the team with his teammate Patrick Tambay finishing second.
At the season-ending South African Grand Prix at Kyalami, Riccardo Patrese won the race, but Nelson Piquet finished fourth to secure his second Drivers' World Championship, beating Alain Prost by just two points.
