The 1966 French Grand Prix was a Formula One motor race held at Reims on 3 July 1966. It was race 3 of 9 in 1966 Formula One Season. The race was the "60th Anniversary race" of Grand Prix racing, which had started with the GP of France in 1906.

The race was won by the 1959 and 1960 World Champion, Australian driver Jack Brabham, driving his Brabham BT19. It was his first win since establishing his Brabham team, and the first win for the Australian-developed Repco-Brabham V8 engine. Brabham became the first driver to win a World Championship Grand Prix in a car bearing his own name. British driver Mike Parkes finished second in a Ferrari 312 while Brabham's team-mate, New Zealander Denny Hulme, finished third in his Brabham BT20.
