Lake Saint-Louis, or in French Lac Saint-Louis, is a lake in southwestern Quebec, Canada, adjoining the Island of Montreal at the confluence of the Saint Lawrence and Ottawa Rivers.

The lake is bounded to the north and east by the Island of Montreal. Additionally, it is bounded by the Regional County Municipalities of Beauharnois-Salaberry, Roussillon, and Vaudreuil-Soulanges.

The town of Beauharnois with its power-dam and canal lie to the south. The lake contains a part of the Saint Lawrence Seaway, joining the South Shore and Beauharnois canals.

To the west, at the lock in Sainte-Anne-de-Bellevue, the lake connects to the Lake of Two Mountains.

The West Island shore is mostly built-up with private houses, but includes some parks and clubs for yachting, sailing, and canoe-kayak.

Islands in the lake include l'Île-Dorval, les Îles de la Paix National Wildlife Area, and Dowker Island.

Many species of fish are present in the lake, including yellow perch.
