Charlesbourg is a provincial electoral district in the Capitale-Nationale region of Quebec, Canada that elects members to the National Assembly of Quebec. It consists of part of the Charlesbourg borough of Quebec City. It was created for the 1973 election from parts of Chauveau and Montmorency electoral districts. In the change from the 2001 to the 2011 electoral map, it lost very small amounts of territory to Jean-Lesage and Montmorency electoral districts.
