Kosteletzkya pentacarpa is native to the coastal wetlands of the Gulf of Mexico, the east coast of the United States (from Florida and Texas up to New York), the Bermudas and Cuba (Alexander et al. 2012). The species is also found in Mediterranean Europe: in Eastern Spain (Llobregat delta, Albufera/Valencia, Balearic islands), France (Corsica) and Italy (Latium and Apulia). Due to its economic use, there was doubt whether the species was native or introduced to Spain, but recent research showed that it is native. Populations occurring in north Italy are considered to be introduced.In Georgia Kosteletzkya pentacarpa grows on only one location in the Anaklia mire in the western part of Kolkheti. In Iran and Azerbaijan the species is found in Talish (Lenqoran) along the west and south coasts of the Caspian Sea. In Russia the species is found along the Volga and along the Don River.
