Piercys Mill is an unincorporated community in Greenbrier County, West Virginia, United States. Piercys Mill is 10.8miles north-northeast of Alderson.
Within the community is Piercy's Mill Cave, a privately-owned cavern that extends just under a mile.[2] A stream flows out of the cave's mouth and into Muddy Creek, a tributary of the Greenbrier River. A side passage inside of Piercy's Mill Cave leads to a series of rimstone dam rooms.[3]
