Clear Fork (Cumberland River tributary)

The Clear Fork is a 42.8 mi tributary of the Cumberland River in Kentucky and Tennessee. By the Cumberland and Ohio rivers, it is part of the Mississippi River watershed.

The Clear Fork rises in Bell County, Kentucky, just north of the Tennessee state line. It flows west-southwest, crossing into Claiborne County, Tennessee, and passing the village of Clairfield. Turning more to the northwest, it crosses into Whitley County, Kentucky, and continues to the Cumberland River just east of Williamsburg.

The river is paralleled by Tennessee State Route 90 for much of its upper course, then by U.S. Route 25W and Tennessee State Route 9 to the Kentucky border. In Kentucky, the river valley is used by U.S. Route 25W and Interstate 75.
