Robec is a small river in Normandy, France. Its length is only 9 km. The river begins near Fontaine-sous-Préaux , then into Darnétal and ends in the Seine near Rouen. Its drainage area includes the Aubette.
In order to avoid a repetition of the floods that have affected the valleys of the Cailly, the Robec and the Aubette, a schéma d'aménagement et de gestion des eaux (water resource management scheme) is under consideration.
