Hog Island Shoal Light, built in 1901, is a sparkplug lighthouse on a shoal off of Hog Island, Rhode Island.

It was built to replace a light ship. 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.
