Lake Le Royer is a freshwater body integrated into a set of lakes designated "Obatogamau Lakes", within the Eeyou Istchee James Bay (municipality) area, within the administrative region of Nord-du-Québec, province of Quebec, Canada. This lake extends in the townships of Fancamp and La Dauversière. Forestry is the main economic activity of the sector. Recreational tourism activities come second. The hydrographic slope of Lac Royer is accessible by a branch of a forest road connecting to the north at route 113 (linking Lebel-sur-Quévillon and Chibougamau) and the Canadian National Railway.
