Hog Island Shoal Light, built in 1901, is a sparkplug lighthouse on a shoal off of Hog Island, Rhode Island. It is located about 600 feet (180 m) southeast of the island, at the entrance to Mount Hope Bay. It stands on a circular concrete foundation set in about 10 feet (3.0 m) of water, and rising about 6 feet (1.8 m) above the water line. It was built to replace a light ship, and was the last light station formally established in the state. The lighthouse was automated in 1964. In 1988 it was added to the National Register of Historic Places. In 2006 the lighthouse was auctioned by the GSA as government surplus to a private buyer.
The light was listed on the National Register of Historic Places in 1988.
