The Copper Country strike of 1913–1914 was a major strike affecting all copper mines in the Copper Country of Michigan. The strike, organized by the Western Federation of Miners, was the first unionized strike within the Copper Country. It was called to achieve goals of shorter work days, higher wages, union recognition, and to maintain family mining groups. The strike lasted just over nine months, including the Italian Hall disaster on Christmas Eve, and ended with the union being effectively driven out of the Keweenaw Peninsula. While unsuccessful, the strike is considered a turning point in the history of the Copper Country.

The Keweenaw Peninsula is the site of many rich native copper deposits. This copper was originally mined by native miners, and many French and British explorers noted the richness of the deposits in the area. Douglass Houghton explored the area in 1831 and 1832, and surveyed the peninsula in 1840 as Michigan State Geologist. Houghton's report of 1841 spent more than twenty-seven pages discussing the copper and copper ore. He famously concluded: "the copper ores are not only of superior quality, but also that their associations are such as to render them easily reduced." He noted that samples of ore he had tested were richer than the copper ore being then mined in Cornwall. Houghton's report prompted a major rush of settlers to the peninsula.

While most of the early mines failed, a few became successful, and eventually several major mines became established. The Copper Country quickly became the first major copper mining region in the United States. By 1913, the majority of copper in the Copper Country was produced by three companies: the Calumet and Hecla Mining Company, by far the largest and richest mine in the Copper Country, as well as the Quincy Mine and the mines owned by the Copper Range Company.
