As of the 2020 census, the population was 13,124.[1] The county seat is Hardin.[2] The county, like the river and the mountain range, is named after the bighorn sheep in the Rocky Mountains.[3] The county was founded in 1913.[4] It is located on the south line of the state.
Most of the area is part of the Crow Indian Reservation. Reservation poverty affects the county, which is the second-poorest county in the state.
