The Gosselin River (in French: rivière Gosselin) is a tributary of Nicolet River passing through Saint-Norbert-d'Arthabaska, Saint-Christophe d'Arthabaska and Victoriaville, in the regional county municipality (MRC) of Arthabaska Regional County Municipality, in the administrative region of Centre-du-Québec, in Quebec, in Canada.

The Gosselin River sometimes flows in agricultural, forest and urban areas.

The neighboring watersheds of the Gosselin River are:

• north side: Bulstrode River, l'Abbé River, Lachance River;
• east side: Gobeil stream;
• south side: Nicolet River, Roux stream, Brooks River;
• west side: Nicolet River.

The Gosselin River takes its source from a small lake located to the east of the Arthabaska sector of the city of Victoriaville and to the east of Mont Saint-Michel.

From its head, the Gosselin river flows on 18.7 kilometres (11.6 mi) in the following segments:

• 8.0 kilometres (5.0 mi) northward, to the confluence of Houle brook;
• 6.7 kilometres (4.2 mi) southwesterly, to the confluence of the Lachance River;
• 3.5 kilometres (2.2 mi) southwesterly, crossing the Arthabaska sector of the city of Victoriaville, to route 116;
• 0.5 kilometres (0.31 mi) towards the southwest, until its confluence.

Note: The course of the Gosselin river completely bypasses Mont Saint-Michel on the north side.

The mouth of the Gosselin River flows onto the north shore of the Nicolet River. Its confluence is located in the south-central part of the city of Victoriaville, on the west side of route 116 and north of avenue Pie-X.

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