West Logan is a town along the Guyandotte River in Logan County, West Virginia, United States. The population was 400 at the 2020 census. For unknown reasons, some sources report West Logan to lay west of the county seat at Logan, attributing to this fact the name.

The Guyandotte River is a tributary of the Ohio River, approximately 166 mi (267 km) long, in southwestern West Virginia in the United States. It was named after the French term for the Wendat Native Americans. It drains an area of the unglaciated Allegheny Plateau south of the Ohio between the watersheds of the Kanawha River to the northeast and Twelvepole Creek and the Big Sandy River to the southwest. Via the Ohio River, it is part of the Mississippi River watershed.
