The Stonington Harbor Light is a historic nineteenth century lighthouse located on the east side of Stonington Harbor in Stonington, Connecticut. A light housed in a small granite lighthouse known by this name was originally built by the federal government in 1824, and was located on Windmill Point in the harbor. Erosion led to the lighthouse being torn down and relocated to its current site in 1840. A second stone building was constructed and the 35 feet (11 m) tower was attached to the structure.
