The 1986 German Grand Prix was a Formula One motor race held at the Hockenheimring on 27 July 1986.

The 45-lap race was won by Brazilian driver Nelson Piquet, driving a Williams-Honda.

Compatriot Ayrton Senna was second in a Lotus-Renault, with Briton Nigel Mansell third in the other Williams-Honda.

Frenchman Alain Prost was running third in his McLaren-TAG in the closing laps when he ran out of fuel, dropping him to sixth and thus allowing Mansell to extend his lead in the Drivers' Championship to seven points.

In the run-up to the race, Keke Rosberg announced that he would be retiring from Formula One at the end of the season, while Lotus announced that they would be using Honda engines in 1987, following Renault's withdrawal from the sport, with Japanese driver Satoru Nakajima replacing Johnny Dumfries.
