The Epte (French pronunciation: [ɛpt]) is a river in Seine-Maritime and Eure, in Normandy, France.

[1] The river rises in Seine-Maritime in the Pays de Bray, near Forges-les-Eaux, and empties into the Seine not far from Giverny.

In 911 the Treaty of Saint-Clair-sur-Epte established the river as the historical boundary of Normandy and Île-de-France.

Claude Monet lived at Giverny near the river for more than forty years.

The river appears in a number of his works, including Peupliers au bord de l'Epte.
