The rivière de la Fourche (in English: river of the Fork) crosses the municipality of Saint-Philémon (MRC Les Etchemins Regional County Municipality), as well as Notre-Dame-Auxiliatrice-de-Buckland and Armagh, in the Bellechasse Regional County Municipality, in the administrative region of Chaudière-Appalaches, in Quebec, in Canada .

The Fourche River is a tributary of the south shore of the rivière du Sud (Montmagny) which flows north-west, then north-east to the south shore of the St. Lawrence River.

[1] The Fourche river takes its name from the fact that the three head waterways (rivière des Orignaux, brook of Milieu and brook Beaudoin) converge together, forming a fork on the maps geographical areas, the handle of which points to the north-west.

[1] The toponym “rivière de la Fourche” was made official on September 11, 1987, at the Commission de toponymie du Québec.
