Robins Island is a 435-acre undeveloped island in Peconic Bay by the eastern end of Long Island. The island is privately owned and not accessible to the public and is within the jurisdiction of Town of Southold in Suffolk County, New York in the USA.
Robins Island is currently owned by Wall Street financier Louis Bacon, who purchased it in 1993 for $11 million. A conservation easement in 1997 makes it unlikely that any development will occur on the island. Bacon has invested considerably in restoring the neglected island, going so far as to import full-grown oak trees to replace ones harvested for lumber years earlier. Some non-native grasses were removed from the island and replaced, and hunters reduced an overgrown deer population. Bacon is known for hosting traditional English “driven pheasant” hunts on the island for wealthy guests.
