The Rivière Noire (English: Black River) is a tributary of the east bank of the Saint-Maurice River, flowing south on 3.6 kilometres (2.2 mi) in the territory of Hérouxville from the MRC Mékinac and south-west on 4.2 kilometres (2.6 mi) in Shawinigan (Saint-Georges-de-Champlain sector), in the administrative region of Mauricie, in Quebec, in Canada.

The river flows a priori towards the south in Hérouxville, then enters the territory of the old village municipality of Saint-Georges (today a sector of the city of Shawinigan).

It then crosses the Saint-Georges-de-Champlain sector, recovering water, in particular from the "Trahan branch" at 1.9 kilometres (1.2 mi) from its mouth.

The waters flow into a long bay which forms an appendix to the artificial reservoir generated by the hydroelectric dam erected on the Saint-Maurice River, in the Saint-Georges-de-Champlain sector of the town of Shawinigan.

The Black River toponym was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.
