The rivière à la Carpe is a tributary of the eastern shore of the Métabetchouane River, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. Entirely in a forest zone, the course of this river crosses the unorganized territory of Belle-Rivière, in the Lac-Saint-Jean-Est Regional County Municipality and the municipality of Saint-André-du-Lac-Saint-Jean, in the Le Domaine-du-Roy Regional County Municipality.
Forestry is the main economic activity in this area; recreational tourism, second.
The surface of the "rivière à la Carpe" (except the rapids zones) is usually frozen from the end of November to the beginning of April, however the safe circulation on the ice is generally done from mid-December to the end of March.

The Carp River takes its source at the mouth of Lac Neuf (length: 1.4km (00.9miles); altitude: 375m (1,230feet)). This lake receives two streams which are surrounded by marshes.

From the confluence of the Carpe river, the current descends the Métabetchouane River north on 11.9km (07.4miles) to the south shore of Lac Saint-Jean; from there, the current crosses the latter on 22.8km (14.2miles) towards the northeast, then borrows the course of the Saguenay River via la Petite Landfill on 172.3km (107.1miles) until Tadoussac where it merges with the Saint Lawrence estuary.[1]
The toponym "rivière à la Carpe" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.[2]
