The Dakota Territory legislature created the county on June 2, 1883, with territories partitioned from Griggs and Traill counties. It was not organized at that time, but was attached to Traill for administrative and judicial purposes. It was named for businessman Edward H. Steele, who had pushed for its creation.
On July 13, 1883, the county organization was effected and Steele County was detached from Traill County; Sherbrooke, North Dakota was chosen as the county seat. In 1897 the town of Finley was founded, and by 1919 its growth had eclipsed Sherbrooke to the point that the county seat was transferred to Finley.[3] The county's boundaries have been unchanged since its creation.

In 2020, Joe Biden fared even worse despite a national increase for the Democratic Party from 2016. He was the first Democrat to win without the county since John F. Kennedy in 1960, and had the lowest proportion of the county's vote of any winning Democrat since Woodrow Wilson in 1912. Since 1964 Steele County has favored the Democratic presidential candidate in 64% of elections.
