Chomedey is a provincial electoral district in Quebec, Canada that elects members to the National Assembly of Quebec. It is located in the western part of Laval. It takes in part of the Chomedey neighbourhood. It includes most of the territory bounded by the Rivière des Prairies to the south, Autoroute 15 to the east, Autoroute 440 to the north and Autoroute 13 to the west.

It was created for the 1981 election from parts of Fabre and Laval electoral districts.

In the change from the 2001 to the 2011 electoral map, it lost some territory to Fabre.

The district is named after Paul de Chomedey, Sieur de Maisonneuve, who founded Ville-Marie (now Montreal) in 1642.
