The Manouane River, a tributary of the Peribonka River, flows in unorganized territory of Mont-Valin, Quebec, in the administrative region of Saguenay-Lac-Saint-Jean, in Quebec, Canada.

This name is from Montagnais source, Manauan Shakaikan meaning "lake where we collect eggs".

This designation turns out to be a derivative of manneu, meaning "he removes it by hand", from uau, egg, and shakaikan, lake.

It would be a custom for the Montagnais to collect the eggs of birds in the islands and on the shores of this lake.

The toponym "Rivière Manouane" was inscribed on December 5, 1968, at the Bank of Place Names of the Commission de toponymie du Québec.
