Nomans Land, is an uninhabited island 612 acres in size, located in the town of Chilmark, Dukes County, Massachusetts. It is situated about 3 miles off the southwest corner of the island of Martha's Vineyard.
The island was used by the United States Navy as a practice bombing range from 1943 to 1996. In 1998, the Navy transferred the island to the United States Fish and Wildlife Service for use as an unstaffed wildlife refuge, which now forms Nomans Land Island National Wildlife Refuge. Due to safety risks from unexploded ordnance and its value as a wildlife habitat, the island is closed to all public use.
