Quebec City (French: Ville de Québec, or simply Québec) ( or /kəˈbɛk/) is the capital of the Canadian province of Quebec, making it the seat of the provincial Crown. It is the second largest city in the province, after Montreal. Quebec City's Old Town (Vieux-Québec) is the only North American fortified city north of Mexico whose walls still exist, and was declared a World Heritage Site by UNESCO in 1985 as the "Historic District of Old Quebec". It is also one of the oldest cities in North America (founded in 1608). The city has a population of 528,595, and the metropolitan area has a population of 717,600 (2005).

Quebec City is internationally known for its Summer Festival, Winter Carnival and the Château Frontenac, a historic hotel which dominates the city skyline. The chief of Parliament, the National Assembly of Quebec (provincial parliament), the Musée national des beaux-arts du Québec (National Museum of Fine Arts) and the Musée de la civilisation (Museum of Civilization) are found within or near Vieux-Québec.
