The Clear Fork is a tributary of the Guyandotte River, 29 miles (47 km) long,[3] in southern West Virginia in the United States.

Via the Guyandotte and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 129 square miles (330 km2)[4] in a rural area on the unglaciated portion of the Allegheny Plateau.

The Clear Fork flows for its entire length in Wyoming County; its tributary the Laurel Fork also drains a small area of western Raleigh County.

[5] The Clear Fork rises in northern Wyoming County, approximately 2 miles (3.2 km) west of Bolt, and flows generally southwestward through the communities of Crany, Toney Fork, Oceana, Lillyhaven, Lillydale, Clear Fork, and Sun Hill.

It flows into the Guyandotte River from the east, to the southeast of the community of Simon in the R.D.
