The rivière du Moulin crosses the municipalities of Saint-Lazare, Saint-Nérée and Saint-Gervais, in the Bellechasse Regional County Municipality, in the administrative region of Chaudière-Appalaches, in Quebec, in Canada.

The Moulin river is a tributary of the south bank of the Bras Saint-Michel, which flows north-east to empty onto the north-west bank of the rivière du Sud (Montmagny); the latter flows north-east to the south shore of the St. Lawrence River.

The Moulin River has its source in the sixth rang East, at 1.7 kilometres (1.1 mi) northeast of the center of the village of Saint-Lazare. From its source, the Moulin river flows over 20.3 kilometres (12.6 mi), divided into the following segments:

• 4.4 kilometres (2.7 mi) east, then north in Saint-Lazare, up to the limit of Saint-Nérée;
• 4.9 kilometres (3.0 mi) northeasterly, curving northeasterly to the boundary between the municipalities of Saint-Nérée and Saint-Gervais;
• 4.1 kilometres (2.5 mi) north-west to a road;
• 3.6 kilometres (2.2 mi) north-west to a road that crosses the Faubourg-du-Moulin;
• 2.2 kilometres (1.4 mi) northward to the confluence of the Larochelle stream;
• 1.1 kilometres (0.68 mi) north, up to its confluence.^[1]

The Moulin River empties on the south shore of Bras Saint-Michel in the municipality of Saint-Gervais (at the limit of Saint-Charles-Borromée). This confluence is located at 4.5 kilometres (2.8 mi) north of the center of the village of Saint-Gervais, at 9.1 kilometres (5.7 mi) south of the center from the village of La Durantaye.

The toponym Rivière du Moulin was made official on January 21, 1975, at the Commission de toponymie du Québec.^[2]
