Archaeological evidence shows that the site has been in use for at least 8,000 years. Robert Campbell established a Hudson's Bay Company trading post nearby in 1848. In early 1852 he moved the post to its current location. Resenting the interference of the Hudson's Bay Company with their traditional trade with interior AthabaskanFirst Nations, Chilkat Tlingit warriors attacked and looted the post that summer. It was rebuilt about 40 years later and became an important supply point along the Yukon River. It was essentially abandoned by the mid-1950s after the Klondike Highway bypassed it and Yukon River traffic died down.
At age 28, under the command of Inspector John Douglas Moodle, Francis Joseph Fitzgerald was the first to chart an overland route from Edmonton to Fort Selkirk, Yukon via northern British Columbia and the Pelly River (1897). The voyage took eleven months, having covered about 1,000 miles. As a result of this achievement, Fitzgerald was promoted corporal in 1899.
Many of the buildings have been restored and the Fort Selkirk Historic Site is owned and managed jointly by the Selkirk First Nation and the Yukon Government's Department of Tourism and Culture. There is no road access. Most visitors get there by boat, though there is an airstrip, Fort Selkirk Aerodrome, at the site.
