The Rock Springs massacre, also known as the Rock Springs riot, occurred on September 2, 1885, in the present-day United States city of Rock Springs in Sweetwater County, Wyoming. The riot, and resulting massacre of immigrant Chinese miners by European immigrant miners, was the result of racial prejudice toward the Chinese miners, who were accused of taking jobs from the existing miners. The Union Pacific Coal Department found it economically beneficial to give preference in hiring to Chinese miners, who were willing to work for lower wages than their European counterparts, which angered the existing miners. When the rioting ended, at least 28 Chinese miners were dead and 15 were injured. Rioters burned 78 Chinese homes, resulting in approximately $150,000 in property damage (equal to $4,800,000 in 2025 terms). Despite the identification of the perpetrators, no individuals were prosecuted for the murders or property destruction.
Tension between European and Chinese immigrants in the late 19th-century American West was particularly high, especially in the decade preceding the violence.
