West Island is an unofficial name for the cities, towns, and boroughs located at the western end of the Island of Montreal in Quebec, Canada. It serves as a geographical designation rather than a single incorporated municipality.
The region generally consists of several Lakeshore municipalities, including Lachine, Dorval, Pointe-Claire, and Beaconsfield. Other included areas are Kirkland, Dollard-des-Ormeaux, Baie-D'Urfé, Sainte-Anne-de-Bellevue, and the village of Senneville. Additionally, it encompasses two North Shore boroughs of the city of Montreal: Pierrefonds-Roxboro and L'Île-Bizard–Sainte-Geneviève.
