Pointe-des-Cascades is a village municipality in Vaudreuil-Soulanges Regional County Municipality in the Montérégie region of Quebec, Canada. It is located on a spit of land where the St. Lawrence River flows into Lake Saint-Louis. The river has here a significant drop, forming several cascades which give the village its name. The islands of Île des Cascades and Île des Joybert are connected by a narrow causeway, but Île des Cascades and Pointe-des-Cascades are only connected artificially.
