The Greenwich Cove Site in Warwick, Rhode Island, is a prehistoric archaeological site on a knoll above Narragansett Bay with evidence of use from the Late Archaic through the Middle Woodland period. Discovered during residential construction in 1976, it contained both a shell midden and a habitation area near a kettlehole that provided the only fresh water. Salvage excavations in 1979 uncovered traces of daily life and toolmaking, including pottery fragments, stone chips, bone fragments, fire-hardened stone, organic remains, a hearth, bone tools, and stone for implements. The site is especially significant for its moderately well-preserved coastal shell midden and its long record of prehistoric occupation.
