La Tuque is a city located in north-central Quebec, Canada, on the Saint-Maurice River, between Trois-Rivières and Chambord. The population was 11,227 at the Canada 2011 Census, most of which live within the urban area.

While the urban area of La Tuque is relatively small, as of 2012, its entire territory is the largest municipality in Canada. It consists of almost all the entire former regional county municipality of Le Haut-Saint-Maurice, and includes the settlements of Carignan, La Croche, Fitzpatrick, Oskelaneo, Parent, Rapide-Blanc, Rivière-aux-Rats, and Sanmaur. Enclosed by but administratively not part of the city are the three Indian Reserves of Coucoucache, Obedjiwan, and Wemotaci.
