Quebec (/kwɨˈbɛk/ or /kəˈbɛk/), French: Québec ([keˈbɛk] ( listen)), also Quebec City or Québec City (French: Ville de Québec) is the capital of the Canadian province of Quebec and is located within the Capitale-Nationale region. It is the second most populous city in the province – after Montreal, about 233 kilometres (145 mi) to the southwest. As of the 2006 Canadian Census, the city has a population of 491,142, and the metropolitan area has a population of 715,515.

The narrowing of the Saint Lawrence River approximate to Quebec City and Lévis, on the opposite bank, provided the name given to the city, Kébec, an Algonquin word meaning "where the river narrows". Founded in 1608 by Samuel de Champlain, Quebec City is one of the oldest cities in North America. The ramparts surrounding Old Quebec (Vieux-Québec) are the only remaining fortified city walls that still exist in the Americas north of Mexico, and were declared a World Heritage Site by UNESCO in 1985 as the 'Historic District of Old Québec'.

Quebec City is internationally known for its Summer Festival, Winter Carnival, and the Château Frontenac, a hotel which dominates the city skyline. The National Assembly of Quebec, the Musée national des beaux-arts du Québec (National Museum of Fine Arts of Quebec), and the Musée de la civilisation (Museum of Civilization) are found within or near Vieux-Québec. Among the other attractions near the city are Montmorency Falls and the Basilica of Sainte-Anne-de-Beaupré in the town of Sainte-Anne-de-Beaupré.
