The Brock River is a tributary of the Chibougamau River, flowing in Eeyou Istchee Baie-James, in the administrative region of Nord-du-Québec, in the province of Quebec, in Canada. The course of the river crosses successively (from the upstream) the cantons of Beaulieu, Cherisy, La Rochette, Rageot, Livillier, La Touche and Opémisca.

The hydrographic slope of the "Brock River" is accessible by a forest road that cuts across the northern part of the river, at 1.7 kilometres (1.1 mi) south of Villebois Lake. This road comes from the South where it separates from the route 113 which connects Lebel-sur-Quévillon to Chibougamau and passes to the South of the lake.

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