Sheridan County is a county in the U.S. state of Montana. As of the 2020 census, the population was 3,539.[1] Its county seat is Plentywood.[2] Its northern boundary is the Canada–United States border south of Saskatchewan.
The Montana Legislature established Sheridan County in 1913 from portions of Dawson and Valley Counties. It was named for American Civil War General Philip Sheridan.[3] In the 1920s and 1930s the county was a hotbed of communist organizing. The CPUSA managed to elect several town and county officials. At the 1932 presidential election the communist candidate William Z. Foster got 576 votes (22%).[4] International changes in communist organizing strategies, especially the move towards the popular front, effectively ended communist presence in the area.[5]
According to the United States Census Bureau, the county has a total area of 1,706 square miles (4,420 km2), of which 1,677 square miles (4,340 km2) is land and 29 square miles (75 km2) (1.7%) is water.[6]
