Hatteras Island is a barrier island located off the North Carolina coast. Dividing the Atlantic Ocean and the Pamlico Sound, it runs parallel to the coast, forming a bend at Cape Hatteras. It is part of North Carolina's Outer Banks and includes the communities of Rodanthe, Waves, Salvo, Avon, Buxton, Frisco, and Hatteras. It contains the largest part of the Cape Hatteras National Seashore. Prior to European settlement the island was inhabited by Croatoan Native Americans.
