U.S. Route 231 (US 231) in Kentucky runs 86.465 miles (139.152 km) from the Tennessee state line near Adolphus to the William H. Natcher Bridge on the Ohio River (Indiana state line) near Rockport, Indiana. It crosses the state mainly in the west-central region, traversing Allen, Warren, Butler, Ohio, and Daviess Counties.

Running concurrently with U.S. Route 31E for its first 8.607 miles (13.852 km) in Kentucky, US 231/31E enters the state from Sumner County, Tennessee, and into Allen County. The two routes separate on the west side of Scottsville after the KY 100 junction. US 231 turns northwestward into a four-lane highway on its way into Warren County, and into Bowling Green. Just before leaving the city, US 231 crosses the William H. Natcher Parkway for a second time (the first was at the parkway's southern terminus).

US 231 reaches Butler County to cross the Natcher Parkway for a third time, and running concurrently with KY 79 into Morgantown. KY 70 joins in on the concurrency as US 231, KY 79, and KY 70 cross the Green River. Both state routes separate in the Aberdeen area before crossing the Natcher Parkway for a fourth and final time before entering Ohio County. It meets U.S. Route 62 in the Beaver Dam/Hartford area after crossing the Wendell H. Ford Western Kentucky Parkway on the south side of Beaver Dam.
