Idaho County is a county located in the U.S. state of Idaho. As of the 2010 census, the population was 16,267.[1] The county seat is Grangeville.[2] Previous county seats of the area were Florence (1864–75) and Mount Idaho (1875–1902).

Idaho County was originally founded as a region of Washington Territory in 1861, named for a steamer called Idaho that was launched on the Columbia River in 1860. It was reorganized by the Idaho Territorial Legislature on February 4, 1864. In this context, the name of the county predates both the Idaho Territory and the State of Idaho.

Idaho County is one of seven counties in the United States that has the same name as the state in which it lies. The other six are Arkansas, Hawaii, Iowa, New York, Oklahoma, and Utah.[3]
