The Sainte-Anne Ouest River is a tributary of the Bras du Nord flowing in the unorganized territory of Lac-Blanc and Lac-Croche, as well as in the town of Saint-Raymond, in the MRC Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada.

[1] The surface of the Sainte-Anne Ouest river (except the rapids) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March.

The Sainte-Anne Ouest river rises at the mouth of Lake Annette (length: 1.4 kilometres (0.87 mi); altitude 626 metres (2,054 ft)).

From there, the current generally descends south following the course of the latter to the northwest bank of the Sainte-Anne River.

[1] The toponym "Rivière Sainte-Anne Ouest" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
