Reims-Gueux was a triangular road course in Reims, France, which hosted 14 French Grands Prix.

Reims-Gueux was first established in 1925 on the public roads between the small French villages of Thillois and Gueux. The circuit had two very long straights between the towns, and teams strove to maximize straight-light speed of their cars; many slipstream battles ensued. Race organizers actually felled trees and demolished old houses in order to make the circuit even quicker. In 1952, the circuit was significantly altered to bypass the village of Gueux, and many people now refer to the course as simply Reims.

Its first event was the Grand Prix de Marne, staged by the Automobile Club of Champagne. Grand Prix racing came soon thereafter, with the first official Formula One event occurring in 1950, F1's inaugural year. The circuit was last used by Formula One in 1966, and it closed permanently in 1970 due to financial difficulties, although sections of the track around the pit lanes are still visible today.
