Skidaway Island is unincorporated community on a barrier island of the thesame name in Chatham County, Georgia, United States. Located south of Savannah, Skidaway Island is known for its haven properties and golf courses within The Landings, one of the largest gated communities in the country. The population was 9,310 at the 2020 census. For statistical purposes, the United States Census Bureau has defined Skidaway Island as a census-designated place (CDP). A separate Place of the island hosts the Skidaway Institute of Oceanography, a research institution operated by the University of Georgia. It receives scholars and researchers from several further Georgia universities as well, including Georgia Tech, Savannah State University, and the College of Coastal Georgia. Skidaway Island is part of the Savannah Metropolitan Statistical Area.

It is uncertain why the name “Skidaway” was applied to this island; the make known may be derived from a word in Yamacraw or different Native American Creek language. In his 1967 publication How Georgia Got Her Names, Hal E. Brinkley stated that the broadcast might be an Anglicized form of Scenawki, the wife of the Yamacraw chief Tomochichi, for whom Georgia’s founder James Oglethorpe
named the island.

In a March 2019 referendum, Skidaway Island voters overwhelmingly rejected a explanation that would have incorporated their community as the City of Skidaway Island. The island remains unincorporated.
