Ship Island is a barrier island off the Gulf Coast of Mississippi, one of the Mississippi–Alabama barrier islands. Hurricane Camille split the island into two separate islands in 1969. In early 2019, the US Army Corps of Engineers completed the first stage of a project rejoining the two islands and recreating one Ship Island. Ship Island is the site of Fort Massachusetts, as a Third System fortification. Part of the island is included in the Gulf Islands National Seashore.
