The Port au Persil River (French: "Rivière du Port au Persil") is a tributary of the northwest shore of the St. Lawrence River, flowing into the city of Saint-Siméon in the Charlevoix-Est Regional County Municipality, in the Capitale-Nationale administrative region, Quebec, Canada. The course of this river flows into the Saint Lawrence River in the village of Port au Persil, northeast of the city of La Malbaie.
The upper part of the valley of this watercourse is served by Route 138 along the northwest shore of the St. Lawrence River. However, this road spans the river from Port aux Persil to land in order to get around the coast near the river. The riparian zone is served by the Port-au-Persil road which spans the Port-au-Persil River, near its confluence with the Gulf of St. Lawrence.
Forestry is the main economic activity of the sector; recreational and tourism activities (including resort and tourist activities), second.
The surface of this stream is usually frozen from mid-December to the end of March. Nevertheless, safe ice circulation is generally from late December to mid-March.

The Port-au-Persil River rises from a mountain stream (elevation: 281m (922feet)) in a forest area southeast of "lac des Rats Musqués" (lake of the Musk Rats).

The term "Port au Persil" is used in Quebec toponymy in the area of Saint-Siméon to designate: the harbor, the hamlet, the bay, the road, the lake, the river and a street.
The term "parsley" was used in the accounts of Samuel de Champlain in 1626. The word parsley is equivalent to "Ligusticum scothicum" or Scottish fillet or parsley or wild parsley, which abound on the shores of the St. Lawrence River, particularly at Rivière-du-Loup.[4]
The toponym "Rivière du Port au Saumon" was formalized on March 28, 1974 at the Bank of Place Names of the Commission de toponymie du Québec.
