The Cyprus dwarf hippopotamus or Cypriot pygmy hippopotamus (Hippopotamus minor) is an extinct species of hippopotamus that inhabited the island of Cyprus until the early Holocene. The 200-kilogram (440-lb) Cyprus dwarf hippo was roughly the same size as the extant pygmy hippopotamus. Unlike the modern pygmy hippo, the Cyprus dwarf became small through the process of insular dwarfism. This same process is believed to cause the dwarfism found in some dwarf elephants, the pygmy mammoth, and Homo floresiensis. The animal is estimated to have measured 76 cm tall and 121 cm long.
