The Wolf River is a river in the municipality of French River, Sudbury District in Northeastern Ontario, Canada.[1] It is in the Great Lakes Basin and is a right tributary of the Wolseley River.
The river begins at an unnamed lake in geographic Cosby Township[2] and heads east, passes the communities of Noëlville and Chartrand Corner, then turns northwest and reaches Lac Viau on the Wolseley River. The Wolseley flows via the French River to Georgian Bay on Lake Huron.
