Results from the 1985 Formula One San Marino Grand Prix held at Imola on May 5, 1985. Limited fuel allowances played a big part in the race, as a succession of drivers ran out in the last few laps. Alain Prost took the chequered flag before stopping on the slowing-down lap and being found to be 2 kg underweight in post-race scrutineering, meaning disqualification. Nigel Mansell noted that "it wasn't really racing".
