This area was the territory of Western Shoshone, Northern Paiute, and Bannock peoples and their ancestors for thousands of years prior to the arrival of Americans. Conflicts over land use and resources led to the indigenous peoples being pushed aside.

On December 31, 1863, Owyhee County became the first county organized by the Idaho Territory Legislature. While Boise, Idaho, Nez Perce, and Shoshone counties were organized under the laws of Washington Territory, they were not recognized by the Idaho Territory until February 1864. The original county seat at Ruby City was moved to nearby Silver City in 1867.

Owyhee County's original boundary was the portion of Idaho Territory south of the Snake River and west of the Rocky Mountains. Less than a month after the creation of Owyhee County, Oneida County was formed in January 1864 from the eastern portion of the county. The formation of Cassia County in 1879 took further territory in the east.
