The Prudence Island Lighthouse, more commonly known locally as the Sandy Point Lighthouse, is located on Prudence Island, Rhode Island and is the oldest lighthouse tower in the state. Sandy Point is nicknamed Chibacoweda, meaning "little place separated by a passage", because the location is a little more than one mile offshore.

The lighthouse was constructed in 1823 and originally sat on a dike off Goat Island farther south in the Bay, where the Newport Harbor Light stands today. In 1851, it was transported to Prudence Island where it remains. It is one of the few lighthouses in the United States to retain its original bird-cage lantern. The light was listed on the National Register of Historic Places in 1988.

The lighthouse keeper's house was swept away in the 1938 New England hurricane, and five people were washed out to sea and drowned, including the lighthouse keeper's wife. The keeper was also washed into the sea, but he was thrown back ashore and survived.
