The river Bolbec or Commerce 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 Bolbec and passes Gruchet-le-Valasse, where its name changes to the Commerce. It then passes through Lillebonne and joins the Seine at Notre-Dame-de-Gravenchon.

The river hosted many watermills that powered machinery to process both cotton and flax. The area became so prosperous it was named the Golden Valley.
