Bighorn County, Montana is a county located in the U.S. state of Montana on the Crow Indian Reservation and adjacent to the Northern Plains and the Bighorn River. It contains a mix of Bighorn Mountains foothills and river valleys that have drawn explorers, U.S. Route 87, and Fort Custer-era settlers. The county seat is Hardin, a community shaped by interactions among the Crow Tribe of Indians, Sioux Nation, and Euro-American agricultural and energy enterprises.
The region was traversed by the Lewis and Clark Expedition, contested during the Great Sioux War of 1876 and influenced by treaties such as the Treaty of Fort Laramie (1851) and the Treaty of Fort Laramie (1868), which involved the Crow Tribe of Indians and the United States. Military posts including Fort Custer and later Fort Smith affected settlement patterns, while railroad expansion by the Northern Pacific Railway and later routes like the Burlington Northern Railroad facilitated homesteading under laws like the Homestead Act of 1862. Conflicts over land and resources intersected with legal decisions involving the U.S. Supreme Court and federal agencies such as the Bureau of Indian Affairs.

Socioeconomic data are tracked by agencies including the Bureau of Labor Statistics and the Indian Health Service, documenting disparities in health, income, and education tied to historical treaties and federal policies.
The county economy combines energy production, agriculture, and tribal enterprises: oil and gas operations by corporations like ExxonMobil and regional firms, alongside coal and mineral interests examined by the Environmental Protection Agency and the Bureau of Land Management. Ranching and irrigated farming connect to commodity markets administered through the United States Department of Agriculture and agricultural extension programs at the Montana State University Extension. Tourism associated with outdoor recreation near the Bighorn Canyon National Recreation Area and cultural tourism tied to the Little Bighorn Battlefield National Monument and Crow cultural institutions contribute to local revenue, while federal funding from agencies such as the Indian Health Service and the Department of Housing and Urban Development supports community services.
Local governance operates through county offices in Hardin and tribal government by the Crow Tribe of Indians with its own constitution and elected leadership that engages with federal entities such as the Bureau of Indian Affairs and the Department of the Interior. Political dynamics reflect state-level interactions with the Montana Legislature and federal representation in the United States Congress, with voting patterns analyzed by organizations like the National Conference of State Legislatures and the Cook Political Report. Legal matters and litigation have involved the United States District Court for the District of Montana and precedent-setting decisions from the U.S. Supreme Court concerning Native American jurisdiction and resource rights.
