List of National Natural Landmarks in West Virginia
This is a list of the National Natural Landmarks (NNLs) in West Virginia. There are 15 in all — 5 are wetlands (bogs, swamps, etc.), 3 are forests, 6 are limestone caves/karst, and one is a rock formation. (In addition, the Cranesville Swamp Preserve is a NNL mostly in Garrett County, Maryland, a portion of which extends into Preston County, West Virginia.) Ten of the 15 NNLs are within the boundaries of the Monongahela National Forest, although this does not necessarily mean they are on public land.

De-designation
According to a notice in the Federal Register (Vol. 71, No. 138 / Wednesday, July 19, 2006), Swago Karst Area (in Pocahontas County) was removed by the Department of the Interior from NNL designation in response to owner requests. Its citation formerly read: "A classic illustration of features associated with karst topography and terrain, including caverns and other passages. Three miles west of Marlinton."
