The 1961 French Grand Prix (47th Grand Prix of the A.C.F.), held at the Reims circuit on July 2, 1961, was the ninety-eighth race of the Formula One World Championship held since 1950 and the fourth round of the 1961 championship. Virtually as fast as Spa-Francorchamps, the Gueux circuit was used only once a year, in early July, for a meeting that included, in addition to the Formula One Grand Prix, an international Formula Junior cup, named the Jean Behra Challenge in homage to the French champion who had passed away two years earlier. Extending over eight kilometers, the track included two long straights, allowing top speeds of nearly 300 km/h for the earlier F1 cars, whose power approached three hundred horsepower.
