The binni, or Mesopotamic Barbel, Mesopotamichthys sharpeyi, is a species of cyprinid fish endemic to the Tigris-Euphrates river system. This barbel is the only member in its genus, but was included in the "wastebasket genus" Barbus by earlier authors. Not evaluated by the IUCN, it is probably not rare or endangered, though it may have declined notably in recent times due to habitat destruction.
