The Toulnustouc River (French: Rivière Toulnustouc) is a tributary of the Manicouagan River in Rivière-aux-Outardes, Côte-Nord, Quebec, Canada. It is dammed to form Lake Sainte-Anne, which regulates water supply to the huge hydroelectric plants near the mouth of the Manicouagan and also feeds the Toulnustouc generating station with a capacity of 526 MW, which has been operational since 2005.
