The rivière des Aulnaies (English: alders river) is a tributary of the rivière du Milieu, flowing on the west side of the Saint-Maurice River, in the Matawinie Regional County Municipality, in the administrative region of Lanaudière, in the province of Quebec, in Canada. The course of the river crosses the territories of:
- Saint-Michel-des-Saints (municipality): canton of Brassard;
- Baie-de-la-Bouteille (unorganised territory): canton of Laviolette.
The Rivière des Aulnaies is part of the watershed of the Rivière du Milieu, the Taureau Reservoir and the Matawin River; the latter generally flows east to spill onto the east bank of the Saint-Maurice River, which in turn spills to Trois-Rivières on the north bank of the Saint Lawrence River.
The economic activity of the Aulnaies river watershed turns out to be forestry and recreational tourism activities. The course of the river flows entirely in forest areas. The river surface is generally frozen from mid-December until the end of March.
