It is south of the Canada–US border with Manitoba. The Dakota Territory legislature created the county on March 8, 1883, with areas partitioned from Cavalier and Rolette counties. It was named for Oscar M. Towner, a businessman and member of the 15th territorial legislature. The county organization was not completed at that time, and the county was attached to Pembina County for judicial and administrative purposes. That lasted until January 24, 1884, when the county organization was effected, and its attachment to Pembina was dissolved. However, on January 26, 1889, the county was attached to Ramsey County for judicial and administrative purposes. This arrangement only lasted a few months. The boundaries of Towner County, as first formed, have not been altered to the present.
