McLean County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 9,771.[1] Its county seat is Washburn.[2]
The Dakota Territory legislature created the county on March 8, 1883, with areas partitioned from Burleigh, Sheridan, and (now-extinct) Stevens counties. The county was named for John A. McLean, the first mayor of Bismarck.[3] The county organization was completed on November 1 of that year. Its boundaries were altered in 1885, in 1892, and in 1908. It has retained its current configuration since November 3, 1908, when a portion of its previous territory was partitioned to recreate Sheridan County (Sheridan had been dissolved on November 8, 1892, with its territory annexed to McLean).[4]
