Hippopotamus creutzburgi is an extinct species of hippopotamus from the island of Crete. Hippopopotamus colonized Crete probably 800,000 years ago and lived there during the Middle Pleistocene. Bones of H. creutzburgi were found by Dorothea Bate on the Katharo plateau, in eastern Crete, in the 1920s. A similar insular dwarf species, the Cyprus dwarf hippopotamus (Hippopotamus minor) lived on the island of Cyprus until the Holocene. It was at least 20% smaller than either subspecies of Cretan hippo.
