Calgary (IPA: /ˈkælgəriː/) is the largest city in the province of Alberta, Canada.

The city is located in the Parkland region of Alberta. Calgary is the third largest civic municipality, by population, in Canada. As of the 2007 civic census, Calgary's population was 1,019,942. The metropolitan population (CMA) was 1,079,310 in 2006, making Greater Calgary the fifth largest census metropolitan area in the country. Because it is located 298 kilometres (178.8 mi) due south of Edmonton, statisticians define the narrow populated area between these cities as the "Calgary-Edmonton Corridor".

Calgary is well-known as a destination for winter sports and ecotourism with a number of major mountain resorts near the city and metropolitan area.
