The Obatogamau River is a tributary of the Chibougamau River, flowing into the Regional County Municipality (MRC) of Jamésie, in the Nord-du-Québec, in the province of Quebec, in Canada.

The lower and middle portions of the Obatogamau River hydrographic slope can be reached by route 113 which connects Lebel-sur-Quévillon to Chibougamau and the railway; while the northeast side of Obatogamau Lakes is accessible via route 167 and the railway. This road follows in part the valley of the Obatogamau River.

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