The San Marino Grand Prix was a Formula One championship race which was run at the Autodromo Internazionale Enzo e Dino Ferrari in the town of Imola, near the Apennine mountains in Italy, between 1981 and 2006. It was named after nearby San Marino as there already was an Italian Grand Prix held at Monza even though the Imola Circuit was in Italy and not within San Marino's own territory. In 1980, when Monza was under refurbishment, the Imola track was used for the 51st Italian Grand Prix.

The Imola Circuit, officially called the Autodromo Internazionale Enzo e Dino Ferrari, is a 4.909 km (3.050 mi) motor racing circuit. It is located in the town of Imola, in the Emilia-Romagna region of Italy, 40-kilometre (25 mi) east of Bologna. It is one of the few major international circuits to run in an anti-clockwise direction. Initially used for motorcycle racing, the first race at Imola was held in 1953.
