The 1972 French Grand Prix was a Formula One motor race held at the Circuit de Charade in Clermont-Ferrand, Auvergne, France on 2 July 1972.
The Circuit de Charade's natural setting around the base of an extinct volcano created safety concerns due to the dark, volcanic rocks which fell from the mountain onto both sides of the track.

Chris Amon achieved the fifth and final pole position of his career and was leading the race in his Matra until a puncture forced him to pit, leaving Jackie Stewart to win in his Tyrrell-Ford.
