Whitehorse, city and capital (since 1952) ofYukon,Canada, located on theYukon (Lewes) River just below Miles Canyon and the former Whitehorse Rapids (now submerged beneath Schwatka Lake, created after 1958 by a hydropower dam). It is the Yukon headquarters of theRoyal Canadian Mounted Police and is an importanttransportation centre on the Alaska Highway, linked by air to major North American cities. It has long been an outfitting base for anglers, big-game hunters, and trappers.

Whitehorse, perhaps so named because the whitecaps of the rapids on the Whitehorse River resembled the manes of white horses, was founded during theKlondike Gold Rush (1897–98) as a staging and distribution centre; it was the head of river navigation and became the northern terminus of the White Pass and Yukon Route (railway) fromSkagway. MacBride Museum of Yukon History in the city houses pioneer relics, and there are many historic log buildings, including the Old Log Church Museum, the former Anglican Parish Church, where, for a concert in 1904, writerRobert W. Service (then parish secretary) composed “The Ballad of Dangerous Dan McGrew” but, because of its ribald character, decided against reciting it. DuringWorld War II Whitehorse became a construction base for both theAlaska Highway (serving a string of airports) and a crude-oil pipeline from Norman Wells,Northwest Territories, to a local refinery (now closed). Whitehorse was incorporated as a city in 1950, and in 1971 itsmetropolitan area was expanded in the river valley to cover 162 square miles (420 square km). The mining economy,stimulated in the 1950s by a federal program of road construction and financial aid, declined in the 1980s. Government and tourism are the economic mainstays, and the population is increased by the seasonal influx of tourists. Pop. (2006) 20,461; (2011) 23,276.
