Sheridan County was created by the legislature of the Wyoming Territory on March 9, 1888.[3] The county was formed from land ceded from Johnson County. Sheridan County was named for Philip Sheridan, a general in the American Civil War and controversial Indian fighter.[4]

In 1897, Big Horn County was created by removing lands from Sheridan County, along with lands from Fremont County, and Johnson County. The boundaries of Sheridan County were slightly modified in 1911 and 1929, but have remained stable since then.
