Kentucky Route 18 (KY 18), also known as Burlington Pike, is a state highway that serves as a major road through Florence and Burlington in the U.S. state of Kentucky.

It begins at KY 338 (East Bend Road) in the small hamlet of Rabbit Hash and travels north along the Ohio River to the small town of Belleview.

A couple miles east, KY 18 intersects with KY 237 (Camp Ernst Road heading south and North Bend Road heading north).

Continuing east, KY 18 spurs off Mall Road, a commercial road holding much of the commerce in the city of Florence, including the Florence Mall.

East of I-71/I-75, KY 18 turns slightly north in its final couple miles.
