St. Clair was formed by the Alabama Territorial legislature on November 20, 1818. It was named for General Arthur St. Clair (Pennsylvania), a hero of the American Revolution. The county is located in the north-central part of the state, and is bordered by Blount, Calhoun, Talladega, Shelby, and Jefferson counties. It encompasses 646 square miles. St. Clair is the only county in Alabama to have two county seats. Ashville, originally called St. Clairsville, was named for John Ash, a senator in the state's first General Assembly. Located in the northern part of the county, Ashville served as the county seat from 1821-1907.
The Alabama Constitution of 1901 provided for Pell City in the southern part of the county to serve as the county seat for the Southern Judicial District of the county. A constitutional amendment in 1907 established Pell City, named for George H. Pell, an early settler, as the second county seat. Other towns and communities include Ragland and Springville.
As reported by the Census Bureau, the county has a total area of 654 square miles (1,690 km2), of which 632 square miles (1,640 km2) is land and 22 square miles (57 km2) (3.3%) is water.
The Coosa River runs along the eastern border of the county. Because the Coosa River is one of the most heavily used rivers in the state, much of its biological diversity is restricted to its tributaries, which fan out throughout the eastern half of St. Clair County. A series of locks and dams along the Coosa River provide business and recreational opportunities for the county. In addition, a number of tributaries of the Cahaba River flow throughout the western half of St. Clair County, creating scenic views and recreational opportunities.
