Westmount–Saint-Louis is a provincial electoral district in the Montreal region of Quebec, Canada that elects members to the National Assembly of Quebec. It comprises the city of Westmount as well as parts of the Le Plateau-Mont-Royal and Ville-Marie boroughs of Montreal, including most of downtown.
It was created for the 1994 election from parts of Saint-Louis, Westmount and Sainte-Anne electoral districts.
In the change from the 2001 to the 2011 electoral map, it lost a very small amount of territory to the Saint-Henri–Sainte-Anne electoral district.
