Dean Island in the Antarctic is an ice-covered island, 37 kilometres (20 nmi) long and 19 kilometres (10 nmi) wide, lying within the Getz Ice Shelf and midway between Grant Island and Siple Island, off the coast of Marie Byrd Land. It was first sighted from a distance of 37 kilometres (20 nmi) from the USS Glacier on February 5, 1962, and was named for Chief Warrant Officer S.L. Dean, U.S. Navy, Electrical Officer on the Glacier at the time of discovery.
