Kentucky Route 80 (KY 80) is a 483.55-mile-long (778.20 km) state highway in the southern part of the U.S. state of Kentucky. The route originates on the state's western border at Columbus in Hickman County and stretches across the southern portion of the state, terminating southeast of Elkhorn City on the Virginia state line. It is the longest Kentucky State Highway, though the official distance as listed in route logs is much less due to multiple concurrencies with U.S. Route 68 (US 68) and US 23.

The route was split into two segments from 2003 to November 2009. Construction and relocation of KY 80 in Graves, Calloway, and Marshall counties during this time caused the route to be split. A new, four-laned 8.5-mile (13.7 km) section of KY 80 opened in Calloway County on November 25, 2009. The route is now a four-lane divided highway from Mayfield to Bowling Green after the widening to four lanes from Canton to Cadiz was completed in 2020.[citation needed]
