Boisvert River is a tributary of the north shore of Ashuapmushuan Lake, flowing into the unorganized territory of Lac-Ashuapmushuan, Quebec, into the Regional County Municipality (RCM) of Le Domaine-du-Roy, in the administrative region of Saguenay-Lac-Saint-Jean, in Quebec, in Canada.
This river successively crosses the townships of Thibaudeau, Bignell, McCorkill, Rinfret, Vimont, Dollier, Charron and Ducharme. The lower part of the Boisvert River valley runs through the Ashuapmushuan Wildlife Reserve. Forestry is the main economic activity of this valley; recreational tourism activities, second.
The southern part of the Boisvert River valley is served by route 167 which connects Chibougamau to Saint-Félicien, Quebec. Forest Road R1004 (heading northeast) that connects to route 167 serves the northwestern part of the Boisvert River valley and the eastern part of the valley from the Armitage River. The forest road R0210 (North-South direction) serves the eastern part of the valley of the Boisvert River and the valley of the Hogan River. Finally, the R1007 forest road serves the head lake area.
The surface of the Boisvert River is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

The Boisvert River originates at the mouth of an unidentified lake (length: 2.4 kilometres (1.5 mi); altitude: 467 metres (1,532 ft)) located near the northwestern limit of the township of Thibaudeau. This headwater body is located on the eastern side of the water separation line; while the west side has a set of water bodies near a set of bodies of water, including the lakes Terrier, Bignell, Eva and Ida, which flow to the Waconichi Lake; the latest is attached to the southern part of Mistassini Lake.
This head lake of the Boisvert River is located at 2.0 kilometres (1.2 mi) west of a mountain peak of 543 metres (1,781 ft). The mouth of this head lake is located at:
- 16.6 kilometres (10.3 mi) south-east of Waconichi Lake;
- 22.1 kilometres (13.7 mi) south-east of Baie du Poste, south of Mistassini Lake;
- 22.3 kilometres (13.9 mi) northeast of a bay in Chibougamau Lake;
- 45.2 kilometres (28.1 mi) north-east of downtown Chibougamau;
- 62.7 kilometres (39.0 mi) north of the mouth of the Boisvert River (confluence with the Charron Lake);

- 94.4 kilometres (58.7 mi) northwest of the mouth of the Normandin River (confluence with Ashuapmushuan Lake).
From the mouth of the head lake, the Boisvert River flows over 79.9 kilometres (49.6 mi) according to the following segments:
Upper part of the Boisvert River (segment of 28.3 kilometres (17.6 mi)
- 2.7 kilometres (1.7 mi) southerly in the township of Thibaudeau including 2.0 kilometres (1.2 mi) along the boundary between the township of Thibaudeau and the township of Bignell, as well as crossing over 2.0 kilometres (1.2 mi) an unidentified lake that straddles the two townships, to the northern limit of McCorkill Township which is located in the middle of a small lake;
- 2.4 kilometres (1.5 mi) southerly in McCorkill Township through two small unidentified lakes, crossing over Lac Mousse Lake (elevation: 500 metres (1,600 ft) to the limit of the township of Thibaudeau (corresponding to the mouth of the lake);
- 1.4 kilometres (0.87 mi) southerly forming an easterly curve in Thibaudeau Township, returning to the boundary of McCorkill Township;
- 10.7 kilometres (6.6 mi) southwesterly in McCorbill Township, crossing Drouillard Lake (length: 6.5 kilometres (4.0 mi); altitude: 494 metres (1,621 ft) ) on its full length, to its mouth;

The Boisvert River flows into the bottom of a bay on the northeast shore of Charron Lake which the current crosses over 4.3 kilometres (2.7 mi) to its mouth located at route 167. From there, the current crosses Lac la Blanche on 7.4 kilometres (4.6 mi), lake Jordan on 9.8 kilometres (6.1 mi) and Nicabau Lake on 9.7 kilometres (6.0 mi) to the dam at its mouth. From there, the current flows south-east along the Normandin River on 38.7 kilometres (24.0 mi) to the northwestern shore of Ashuapmushuan Lake. Then, the current flows through the Ashuapmushuan River which flows to Saint-Félicien, Quebec on the west shore of Lac Saint-Jean.
