Main image

Gardiners Island is a privately owned island in Gardiners Bay off the eastern end of Long Island, New York. It was acquired by Lion Gardiner in 1639 and has remained in the Gardiner family for generations.

The island is not generally open to the public, so most interest is from historians, researchers and those studying coastal ecology. It contains family properties, farmland and extensive natural habitats that have attracted archaeological and historical study.

Lion Gardiner purchased the island in 1639 and it has remained in private family ownership since then. Over the centuries it has been used for agriculture, as a private residence and as a site of local historical interest.

The island sits in Gardiners Bay off eastern Long Island, between the main body of Long Island and Fishers Island, within the jurisdiction of the Town of East Hampton in New York.

  • Founding: The island has been privately owned by the Gardiner family since it was acquired by Lion Gardiner in 1639.
  • Access: Access is restricted and the island is not open to casual public visits; permission from the owners is required to land.
