Cabell County is located in the U.S. state of West Virginia. As of the 2020 census, the population was 94,350, making it West Virginia's fourth most-populous county. Its county seat is Huntington. The county was organized in 1809 and named for William H. Cabell, the Governor of Virginia from 1805 to 1808. Cabell County is part of the Huntington–Ashland, WV–KY–OH Metropolitan Statistical Area.

William H. Cabell was a Virginia lawyer, politician, plantation owner, and judge aligned with the Democratic-Republican party. He served as a Member of the Virginia House of Delegates, as Governor of Virginia, and as a judge on what later became the Virginia Supreme Court. Cabell adopted his middle initial in 1795—which did not stand for a name—to distinguish himself from other William Cabells, including his uncle, William Cabell Sr.
