The 1924 French Grand Prix, officially named the XVIII Grand Prix de l'A.C.F., was a Grand Prix motor race held at Lyon on 3 August 1924 and the designated European Grand Prix of the 1924 season. The race took place over 35 laps of a shortened version of the circuit used in 1914 for a total distance of 810.09 km.

Grand Prix motor racing, a form of motorsport competition, has its roots in organised automobile racing that began in France as early as 1894. It quickly evolved from simple road races from one town to the next, to endurance tests for car and driver. Innovation and the drive of competition soon saw speeds exceeding 100 miles per hour (160 km/h), but because early races took place on open roads, accidents occurred frequently, resulting in deaths both of drivers and of spectators. A common abbreviation used for Grand Prix racing is "GP" or "GP racing".
