The 1951 French Grand Prix was a Formula One motor race held at Reims-Gueux on 1 July 1951. It was the fourth round of the 1951 World Drivers' Championship and was won by Juan Manuel Fangio and Luigi Fagioli driving an Alfa Romeo. It was the first of three occasions where two drivers would be credited with a Grand Prix win after sharing a car.
The race, which also carried the honorific title of European Grand Prix, saw the World Championship debuts of Aldo Gordini, André Simon and Onofre Marimón. Fagioli's victory, his first in a World Championship race, made him the oldest driver to win a World Championship Grand Prix, a record he still holds.
This race also holds the record for the longest Formula One Grand Prix in terms of total distance needed to cover. 77 laps of the 4.856 mile Reims-Gueux circuit totaled to 373 miles.

About 10 laps into the race, the engine in Fangio's car began misfiring, so he stopped at the pits to have the magneto changed, but only completed one further lap before stopping again. Around this time, the gearbox in Ascari's Ferrari had broken, and he retired, although he took over the car of González, who had been pushing very hard. When Fagioli came in for his fuel stop, the team ordered Fagioli and Fangio to swap cars. Fuel stops and problems for the Ferraris enabled Fangio to make his way into the lead and win the race, with Ascari in González's original car finishing 2nd, 52 seconds behind. Fagioli, in Fangio's original car, finished 11th, 22 laps behind.^1
