History
Fur trappers of the Hudson's Bay Company discovered the Stanley Basin in the 1820s, but it was mostly avoided due to scarcity of beaver. Captain John Stanley, a Confederate Civil War veteran, led a party of twenty-three prospectors through the area in 1863 (or 1864), but they found little gold and moved on and discovered the Atlanta lode on the south end of the Sawtooths. The site was not considered a town until 1919 when its streets and lots were surveyed and recorded.

Stanley has long been a gathering place for the sparsely populated region.

In 2005, Hannah Stauts won the city's mayoral election at age 22 to become the state's youngest elected mayor.
