Piscataway is an extinct Algonquian language formerly spoken by the Piscataway, a dominant chiefdom in southern Maryland on the Western Shore of the Chesapeake Bay at time of contact with English settlers. Piscataway, also known as Conoy (from the Iroquois ethnonym for the tribe), is considered a dialect of Nanticoke.This designation is based on the scant evidence available for the Piscataway language.
