Idaho (ⁱ/ˈaɪdəhoʊ/) is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. To the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of around 1.6 million and an area of 83,569 square miles (216,440 km²), Idaho is the 14th largest and 39th most populous of the 50 states. The state's capital and largest city is Boise.

Idaho prior to European settlement was inhabited solely by Native American peoples, some of which still live in the area. In the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U.S. and the United Kingdom. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead being included for periods in Oregon Territory and Washington Territory. Idaho was eventually admitted to the Union on July 3, 1890, becoming the 43rd state.
