The 1982 San Marino Grand Prix was a Formula One motor race held on 25 April 1982 at the Autodromo Dino Ferrari, Imola, Italy.

The 60-lap race was won by Frenchman Didier Pironi, driving a Ferrari, with Canadian teammate Gilles Villeneuve second and Italian Michele Alboreto third in a Tyrrell-Ford.

After the Renaults of René Arnoux and Alain Prost retired, Villeneuve led from Pironi before the Ferrari team ordered both drivers to slow down, with Alboreto far behind.

In a decision relating to the 1982 Brazilian Grand Prix, Nelson Piquet and Keke Rosberg were excluded for their cars' use of water tanks as ballast to keep them under the weight limit during race conditions.

The Renaults of René Arnoux and Alain Prost qualified first and second, but their cars failed in the race, leaving Ferrari occupying the top two positions with Gilles Villeneuve leading Didier Pironi.
