The '''Rivière Noire Sud-Ouest''' (Black River Southwest) is a tributary of the south shore of the [[Noire River (Charlevoix)|Noire River]] flowing, entirely in the unorganized territory from [[Mont-Élie, Quebec|Mont-Élie]] in [[Charlevoix-Est Regional County Municipality]], in [[Quebec]], [[Canada]].
The lower part of this valley is served by [[Quebec Route 170|route 170]] which links [[Saint-Siméon, Capitale-Nationale, Quebec|Saint-Siméon]] to [[Petit-Saguenay, Quebec|Petit-Saguenay]], which passes on the north shore of the [[Noire River (Charlevoix)|Noire River]]. This valley has some secondary forest roads for forestry and recreational tourism purposes.<ref name=toponymy/><ref name=openstreetmap>[https://tools.wmflabs.org/osm4wiki/cgi-bin/wiki/wiki-osm.pl?project=en&article=Rivière_Noire_Sud-Ouest Open Street Map - Accessed December 8, 2019]</ref>
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.

The "rivière Noire Sud-Ouest" originates at the mouth of Julie Lake (length: {{convert|0.3|km|mi|abbr=on}}; altitude: {{convert|729|m|ft|abbr=on}}). This source is located at:
* {{convert|14.7|km|mi|abbr=on}} south-west of its mouth (confluence with Black River);
* {{convert|25.2|km|mi|abbr=on}} south-west of the mouth of the Black River with the [[Gulf of St. Lawrence]];
* {{convert|4.7|km|mi|abbr=on}} southeast of the head lake of the Petit Saguenay River;
* {{convert|10.4|km|mi|abbr=on}} north-east of the hamlet [[Mont-Grand-Fonds]].
From its source (Lake Julie), the course of the "rivière Noire Sud-Ouest" descends on {{convert|27.9|km|mi|abbr=on}} according to the following segments:
'''Upper South-West Black River''' (segment: {{convert|18.4|km|mi|abbr=on}})
* {{convert|0.5|km|mi|abbr=on}} south, crossing the Cure Lake (length: {{convert|0.5|km|mi|abbr=on}}; altitude: {{convert|728|m|ft|abbr=on}}) on {{convert|0.4|km|mi|abbr=on}} to its mouth;
* {{convert|3.6|km|mi|abbr=on}} east to the Hydro-Québec high-voltage lines;
* {{convert|4.7|km|mi|abbr=on}} northeasterly along the west side of a forest road and passing south-east of the hamlet "Les Jardins" to a creek (coming from the west);
* {{convert|1.1|km|mi|abbr=on}} northeasterly to the forest road bridge;
* {{convert|3.4|km|mi|abbr=on}} northeasterly, passing southeast of Lac au Plongeon, to the bridge of the forest road;
* {{convert|2.8|km|mi|abbr=on}} northeasterly to a bend in the river;
* {{convert|2.3|km|mi|abbr=on}} south-east approaching the foot of the Mountain at Meniche, to a bend of river;
'''Lower South-West Black River''' (segment: {{convert|9.5|km|mi|abbr=on}})
* {{convert|1.9|km|mi|abbr=on}} north to a creek (coming from the west);
* {{convert|4.5|km|mi|abbr=on}} snaking north, collecting the discharge (coming from the southwest) of McLeod Lake and the discharge (coming from the west) of a set of small lakes, up to a stream (coming from the west);
* {{convert|3.1|km|mi|abbr=on}} first forming a hook to the east, then successively to the north, to the west, and to the north where it descends from {{convert|100|m|ft|abbr=on}} to its mouth.<ref name=location>{{cite web|url=http://atlas.gc.ca/toporama/en/index.html|title = Atlas of Canada from the Department of Natural Resources Canada - Characteristics extracted from the map, the databank and the instrumentation of the site|accessdate= December 8, 2019|date = 2016-09-12}}</ref>
