Welcome to
Sheridan County North Dakota!
Sheridan County was named by government officials who prepared the Dakota Territorial map in 1872-1873, after a civil war hero who's name was General Phillip Henry Sheridan.
Although the lines for Sheridan County were drawn in territorial days, Sheridan County was attached to McLean County for judicial purposes. At the general election held on November 3, 1908 in McLean County, the vote was carried by a good majority to divide McLean County and establish Sheridan County effective on January 1, 1909. As is stated above, Sheridan County was already on the Dakota Territorial Map in 1872-1873, however Sheridan County was formally organized January 1, 1909 after the 1908 general election and has had no boundary changes since.
