The Oreille River is a tributary of the Blondeau River (Chibougamau Lake), flowing entirely in the town of Chibougamau, in Jamésie, in the administrative region of Nord-du-Québec, in the province of Quebec, in Canada.

The hydrographic slope of the "Oreille River" is accessible by the junction of a forest road (East-West direction) serving the north side of Chibougamau Lake; the latter is connected to route 167 which also serves the south side of Waconichi Lake and the Waconichi River.

This last road comes from Chibougamau, going north-east to the south-eastern part of Mistassini Lake.

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

The Oreille River originates at the mouth of Lemoine Lake (length: 2.1 kilometres (1.3 mi), altitude: 424 metres (1,391 ft)) in the Township of Roy.
