The Mares of Diomedes (Greek: Διομήδους ἵπποι, translit. Diomēdous hippoi), also called the Mares of Thrace, were a herd of man-eating horses in Greek mythology. Magnificent, wild, and uncontrollable, they belonged to Diomedes of Thrace (not to be confused with Diomedes, son of Tydeus), king of Thrace, son of Ares and Cyrene who lived on the shores of the Black Sea. Bucephalus, Alexander the Great's horse, was said to be descended from these mares.
