Shooters Island is a 43-acre uninhabited island at the southern end of Newark Bay, off the North Shore of Staten Island in New York City. The boundary between the states of New York and New Jersey runs through the island, with a small portion on the north end of the island belonging to the cities of Bayonne and Elizabeth in New Jersey and the rest being part of the borough of Staten Island in New York City.
In colonial times Shooters Island was used as a hunting preserve. During the Revolutionary War, George Washington used the island as a drop-off point for messages, and the place became a haven for spies.
