The river Lézarde is one of the rivers that flow from the plateau of the southern Pays de Caux in the Seine-Maritime département of Normandy into the Seine.
The river rises at Saint-Martin-du-Bec and passes Notre-Dame-du-Bec, Rolleville, Épouville, Montivilliers and joins the Seine at Harfleur. It is 14.2km (08.8miles) long.
In the past, the river was host to many watermills that powered machinery to process both wheat and oil.
