The 1937 French Grand Prix (formally the XXXI Grand Prix de l'Automobile Club de France) was a Grand Prix motor race which was held at Montlhéry, France on 4 July 1937.

The race was won by Louis Chiron driving a Talbot.

Similar to the 1936 race this year was run for sports cars.

However, in order to help French manufacturers prepare for the new 1938 Grand Prix regulations, a 4.5L maximum engine capacity was imposed.
