Marquette River (French: Rivière Marquette, pronounced [ʁivjɛʁ maʁkɛt]) is a tributary of Ashuapmushuan Lake, flowing into the unorganized territory of Lac-Ashuapmushuan, Quebec, into the Regional County Municipality (RCM) of Le Domaine-du-Roy, in the administrative region from Saguenay-Lac-Saint-Jean, in Quebec, in Canada.

The route 167 connecting Chibougamau to Saint-Félicien, Québec passes on the north-east shore of the Normandin River and the Northeast side of Ashuapmushuan Lake.

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

Anxious to found a mission with the Kaskaskias in the Illinois country, Father Marquette must give it up because of illness.

The toponym "Rivière Marquette" was formalized on December 5, 1968, at the Commission de toponymie du Québec.
