Musselshell County is a county in south-central Montana. As of the 2010 United States Census, the population was 4,538. Its county seat is Roundup.
Musselshell County was created in 1911 by Montana Governor Edwin L. Norris. The area was taken from Fergus, from Yellowstone, and Meagher counties. It was named for the Musselshell River which runs southwest–northeast through the county. That river had been thus named in 1805 by the Lewis and Clark Expedition, due to the abundance of freshwater mussels found along its banks. In 1915, a western portion of the county was partitioned off to form Golden Valley County, giving Musselshell County its present boundaries.
The county's northwestern area is rolling grasslands, which slope southeastward to the Musselshell River and the forested Bull Mountains in the southeast. The county has abundant natural resources of coal deposits, subterranean oil, and timbered slopes.
According to the US Census Bureau, the county has a total area of 1,863.91 square miles (4,827.5 km2), of which 1,861.16 square miles (4,820.4 km2) is land and 2.75 square miles (7.1 km2) (0.1%) is water.
In the fourteen national elections after its organization, Musselshell County voters selected Republican presidential candidates 50% of the time, and Democratic candidates 50% of the time. However, since the 1968 election, the Republican candidate has been selected in every election.
