Alosa caspia is a species of clupeid fish, one of the species of shad (genus Alosa) endemic to the Caspian Sea basin.
FishBase treats separately three subspecies from the Caspian:
Previously the taxonomic circumscription and geographic range of A. caspia have been broader, encompassing also the Sea of Azov and Black Sea basins. Up to ten subspecies were recognised; these included forms now classified as Alosa tanaica (and its synonyms) and even the Balkan freshwater endemics Alosa macedonica and Alosa vistonica.
