The 1928 French Grand Prix (formally the XXII Grand Prix de l'A.C.F.) was a Grand Prix motor race held at Saint-Gaudens on 1 July 1928. The race was held over 10 laps of a course for a total distance of . This is the same circuit used for the Grand Prix du Comminges. The race was won by William Grover-Williams driving a Bugatti. Due to a lack of entries in 1926 and 1927 it was decided that the race should be held for sports cars.[1]
Four 10 lap heats were held to determine the starters of the final. The final was run as a handicap race of 10 laps, with handicaps determined by the heats. The eventual winner William Grover-Williams was the last to start, 32 minutes and 8 seconds after the first group of cars was released.[1]
