The Great Salt Pond Archeological District is a historic district in New Shoreham, Rhode Island. The district was added to the National Register of Historic Places in 1990. The Great Salt Pond is a round and almost entirely enclosed body of water separating the north and south regions of Block Island. The pond has a small channel on its north west shore connecting it with Block Island Sound. The opening is artificial and was dug out in 1895 to make a harbor in the south part of the pond.
