The Klondike Gold Rush (1896-1899) was a mass migration of prospectors to Yukon's Klondike region following gold discoveries near Dawson City. An estimated 100,000 people set out for the goldfields, though far fewer completed the arduous journey over mountain passes or up the Yukon River. The Gold Rush transformed Yukon from sparsely populated Indigenous territory to a booming region, leading to creation of Yukon Territory in 1898. Dawson City briefly became one of the largest Canadian cities west of Winnipeg. The Gold Rush left lasting impacts on Yukon's identity, economy, and Indigenous peoples who experienced significant disruption. Gold Rush heritage remains central to Yukon tourism and culture, with historic sites preserved in Dawson City and Whitehorse. Mining continues as an important Yukon industry.
