The Pocatalico River is a tributary of the Kanawha River, about 75 mi (120 km) long, in west-central West Virginia in the United States. Via the Kanawha and Ohio Rivers, it is part of the Mississippi River watershed.
The Pocatalico rises in Roane County near the community of Looneyville and flows generally southwestwardly through southern Roane, northern Kanawha and southeastern Putnam Counties, past the community of Sissonville. It meets the Kanawha River at the town of Poca.
