The Natevier River is a tributary of the Oreille River, flowing entirely into the town of Chibougamau, Jamésie, into the administrative region of Nord-du-Québec, in the province of Quebec, in Canada. The course of the river flows entirely in the canton of Roy. The hydrographic slope of the Natevier River is accessible via 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 Natevier River is usually frozen from early November to mid-May, however, safe ice circulation is usually from mid-November to mid-April. Geography The main hydrographic slopes adjacent to the "Natevier River" are: North side: Waconichi Lake, Mistassini Lake ("baie de Poste"), Barlow River (Chibougamau River); East side: Nepton River, Nepton River North, France River, Boisvert River, Chief River, Chonard River; South side: Oreille River, Blondeau River (Chibougamau Lake), Chibougamau Lake, Armitage River, Énard River; West side: Lake Bourbeau, Chibougamau River, Chevrillon Lake.

Around twenty cottages were built on the north shore of this lake and a small lake upstream. This source of the river is located at: south-west of the mouth of the Natevier River (confluence with the Oreille River); south-east of the bay Route of Waconichi Lake; south-west of Mistassini Lake; north-east of downtown Chibougamau. From the mouth of Cummings Lake, the Natevier River flows over , according to the following segments: north in the township of Roy along route 167 to the bridge of a road junction leading to Lake Bourbeau (located in the West); northeasterly along the northwestern side of route 167, crossing a marsh zone and then crossing over a little unidentified lake (length: ; altitude: ), to its mouth; northeasterly forming an eighth-eighth note to the east where it forms a loop east of route 167, then along this same road on the north-west side and collects the discharge (coming from the west) of Lake Vignon, to the mouth of the river. The Natevier River flows to the west bank of the Oreille River; the latter is a tributary of the North shore of the Blondeau River which flows to the north shore of McKenzie
