Pastinachus is a genus of stingrays in the family Dasyatidae. This genus was long held to be monotypic, containing only the cowtail stingray (P. sephen). Recent studies of Indo-Pacific stingrays have revealed that there are in fact a number of different species of Pastinachus, and that some former junior synonyms may need to be resurrected.
