Portneuf is a provincial electoral district in the Capitale-Nationale region of Quebec, Canada, which elects members to the National Assembly. It notably includes the municipalities of Saint-Raymond, Pont-Rouge, Donnacona and Neuville. It was created for the 1867 election (and an electoral district of that name existed earlier in the Legislative Assembly of the Province of Canada and the Legislative Assembly of Lower Canada). In the change from the 2001 to the 2011, it lost some territory to Laviolette and La Peltrie electoral districts.
