Little Gull Island is a small island in Long Island Sound, located approximately 0.4 miles (0.6 km) northeast of Great Gull Island. Both islands are located in the Town of Southold, in Suffolk County, New York, and lie roughly midway between Plum Island and Fishers Island. Little Gull Island is approximately 4.6 miles (7.4 km) southwest of Fishers Island and the channel of water between them is the main entrance to Long Island Sound, known as The Race.
The Little Gull Island Lighthouse occupies much of the rocky island, which is only about 1-acre (4,000 m2) in size.
