The 1983 San Marino Grand Prix was a Formula One motor race held at Imola on May 1, 1983.
Frenchman Patrick Tambay took a popular victory in his Ferrari in front of a delighted Tifosi. Tambay, who drove the #27 Ferrari dedicated his win to the man he replaced in the Ferrari team, the late Gilles Villeneuve. It was almost a perfect weekend for the Maranello based team with René Arnoux qualifying on pole and finishing 3rd. Renault's Alain Prost finished in second place, passing Arnoux with 3 laps left after the #28 Ferrari spun in the Acque Mineralli chicane.
Brabham driver Riccardo Patrese had taken the lead from Tambay with only 6 laps remaining but only held the lead until he crashed at Acque Mineralli just half a lap later. Showing their love for Ferrari (even with a foreign driver such as Tambay) more than for an Italian driver in a non-Italian car, the Tifosi cheered when Patrese crashed out of the lead and handed it back to the Ferrari.
