Cold Spring Harbor Light was a lighthouse located in Cold Spring Harbor on the north shore of New York's Long Island. It was built in 1890 to mark a shoal at the entrance to Cold Spring Harbor. After the lighthouse was deactivated in 1965, the original light and tower were purchased by a private individual and moved to its current location on land, one mile (1.6 km) to the southwest. An automated light tower and day beacon were erected on the original caisson, and continue to serve as a navigation aid.
