The Little Kanawha River is a tributary of the Ohio River, 169 mi (269 km) long, in western West Virginia in the United States. Via the Ohio, it is part of the watershed of the Mississippi River, draining an area of 2,320 mi² (6,009 km²) on the unglaciated portion of the Allegheny Plateau. It served as an important commercial water route in the early history of West Virginia, particularly in the logging and petroleum industries.
