The Danville River (in French: rivière Danville) is a tributary of the east bank of the Landry River whose current flows successively into the Nicolet Southwest River, Nicolet River, Lake Saint-Pierre and St. Lawrence River. It crosses the municipalities of Saint-Georges-de-Windsor, Saint-Claude and Danville in the Les Sources Regional County Municipality (MRC), in the administrative region of Estrie, in Quebec, in Canada.

 * north side: Nicolet River;

The Danville river has its source at the Lévesque dam in the municipality of Saint-Georges-de-Windsor. This dam retains a body of water 1.4 km in length forming a loop to the south. This body of water is fed by the Jean stream (coming from the north). This dam is located 5.3 km north of the center of the village of Saint-Claude, 5.4 km to the west from the center of the village of Saint-Georges-de-Windsor and south of the village of Asbestos.

From the Lévesque dam, the Danville River flows over 15.5 km in the following segments:
 * 4.5 km towards the north-west, making an incursion on 1.1 km in the municipality of Saint-Claude, until the limit of the municipality of Danville (i.e. the sector of the former municipality of Shipton);
 * 11.0 km northwesterly, into Danville, passing south of the town of Val-des-Sources, crossing route 116, to its mouth.

The Danville River empties on the east bank of the Landry River. Its confluence is located at:
 * 2.3 km (direct line) south of the intersection of route 116 and route 255 of the village of Danville;
 * 5.5 km (or 2.0 km in a direct line) upstream of the confluence of the Landry River.
