Morton County is a county located in the U.S. state of North Dakota. As of the 2010 census, the population was 27,471. Its county seat is Mandan. Morton County and Burleigh County, North Dakota make up the "Bismarck, ND, Metropolitan Statistical Area" or "Bismarck-Mandan".
The county was created by the 1872-1873 territorial legislature and named for Oliver Hazard Perry Throck Morton (1823-1877), governor of Indiana during the American Civil War and later a United States Senator. It was organized on March 23, 1878, but the action of the 1878 legislature in attaching the eastern portion to Burleigh County effectively nullified this action. The county was reorganized on February 18, 1881, after the detached portion had been returned to Morton County by the 1881 legislature. Mandan has always been county seat, though during a period from 1878 to 1879, Mandan, and thus also the county seat, was known as Lincoln.
According to the U.S. Census Bureau, the county has a total area of 1,945 square miles (5,040 km2), of which, 1,926 square miles (4,990 km2) of it is land and 19 square miles (49 km2) of it (0.98%) is water.
