Valmont (French pronunciation: [valmɔ̃]) is a commune in the Seine-Maritime department in the Normandy region in northern France.

A farming village in the Pays de Caux, situated some 32 miles (51 km) northeast of Le Havre, at the junction of the D10, D17, D28 and D69 roads.

The commune was created in 1822 and 1825 by the merger of four former parishes of Valmont, Saint-Ouen-au-Bosc, Rouxmesnil and Le Bec-au-Cauchois.

It was devastated during the Hundred Years' War but was repaired and became a nunnery.

In 1416 the Battle of Valmont took place near the town, as part of the Hundred Years' War.
