Rouen-Les-Essarts was a 5.543 km (3.444 mi) motor racing circuit in Orival, near Rouen, France.

The street circuit (which ran on public roads) had a few medium straights, a cobbled hairpin turn (Nouveau Monde) at the southernmost tip, and a few blind corners through a wooded hillside The appeal was greatly enhanced by the climb from Nouveau Monde at 56 m (184 ft) to Gresil at 149 m (489 ft), with gradients over 9%.
