The Inconnue River (French: Rivière Inconnue) is a tributary of the Maicasagi River located in the municipality of Eeyou Istchee Baie-James, in the administrative region of Nord-du-Québec, in the Canadian province of Quebec, in Canada.

The course of the Inconnue River crosses the townships of Ribourde, Daine, Krieghoff, Montalambert, La Rouvillière and Monseignat.

The hydrographic slope of Inconnue River is served by a secondary road along the North shore of the Waswanipi River and separating from Road 113 connecting Lebel-sur-Quévillon to Chibougamau; as well as by the secondary road R1018 (North-South direction) coming from Matagami and which crosses the Maicasagi River at 14.7 kilometres (9.1 mi) of its mouth.

The surface of the Inconnue River is usually frozen from early November to mid-May, however, safe ice movement is generally from mid-November to mid-April.

The main hydrographic slopes near the Inconnue River are:

The Inconnue River originates at the mouth of Lac La Ribourde (length: 4.2 kilometres (2.6 mi) altitude: 335 metres (1,099 ft)). This lake is connected to Daine Lake on the east side. This source of the river is located at:

From the mouth of the head lake, the "Inconnue River" flows over 68.5 kilometres (42.6 mi) according to the following segments:

Upper part of the Inconnue River (segment of 35.8 kilometres (22.2 mi))

  • 9.8 kilometres (6.1 mi) Southwesterly winding to the eastern limit of the township of Montalembert;

  • 7.1 kilometres (4.4 mi) towards the west, to the eastern limit of the township of Rouvillière;
  • 5.4 kilometres (3.4 mi) Southwesterly to the confluence of a creek (from the southeast);
