Groulx is a provincial electoral district in the Laurentides region of Quebec, Canada, that elects members to the National Assembly of Quebec. It notably includes the city of Boisbriand as well as a few other small cities. It was created for the 1981 election from a part of the Terrebonne electoral district. In the change from the 2001 to the 2011 electoral map, it gained a small part of the city of Blainville from the Blainville electoral district; it did not previously include any part of that city.
