The Aberdeen River is a tributary of the rivière aux Castors Noirs, flowing in the town of La Tuque and in the municipality of Lac-Édouard, in Haute-Batiscanie, in Mauricie, in the province of Quebec, in Canada.

This hydrographic slope is served by some forest roads.

Forestry is the main economic activity in the sector; recreational activities, second.

The surface of the Aberdeen River (except rapids) is generally frozen from early December to late March, but safe circulation on the ice is generally from late December to early March. The water level of the river varies with the seasons and the precipitation.

The Aberdeen River originates from Aberdeen Lake (length: 3.0 kilometres (1.9 mi); altitude: 429 metres (1,407 ft)) in the city's territory from La Tuque. This long, landlocked lake is mainly fed by seven discharges from the surrounding mountains. Its outfall is located at the bottom of a small bay in the southeastern part of the lake.

The Aberdeen River flows to the bottom of a bay on the eastern shore of Lac aux Biscuits. This confluence is located 4.3 kilometres (2.7 mi) northeast of the Canadian National railway, 3.9 kilometres (2.4 mi) northwest of Lac des Trois Caribous, and 6.2 kilometres (3.9 mi) east of the village center of Lac-Édouard.

Aberdeen is the third largest city in Scotland, located in the north-east of Great Britain, on the banks of the North Sea. In Canada, the term Aberdeen is included in some 50 toponyms.

The toponym “Aberdeen River” was formalized on December 5, 1968 in the Place Names Bank of the Commission de toponymie du Québec.
