The Rivière Noire Sud-Ouest (Black River Southwest) is a tributary of the south shore of the Noire River flowing, entirely in the unorganized territory from Mont-Élie in Charlevoix-Est Regional County Municipality, in Quebec, Canada.

The lower part of this valley is served by route 170 which links Saint-Siméon to Petit-Saguenay, which passes on the north shore of the Noire River. This valley has some secondary forest roads for forestry and recreational tourism purposes.[2][3]

Forestry is the first economic activity in the sector; recreational tourism activities, second.

The surface of "rivière Noire Sud-Ouest" is usually frozen from the beginning of December to the end of March, however, safe ice circulation is generally from mid-December to mid-March.
