The Turgeon River is a river flowing through the municipality of the United Townships of Stoneham-et-Tewkesbury, located north of the Quebec (city), in the La Jacques-Cartier Regional County Municipality, in the administrative region of Capitale-Nationale, in the province from Quebec, to Canada.

The upper part of the Turgeon River valley is served by secondary forest roads.

The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

The Turgeon River rises at the mouth of Demers Lake (length: 0.9 kilometres (0.56 mi); altitude: 686 metres (2,251 ft)) located in a forest and mountain area.
