Xiphares (ca. 85 BC – 65 BC) was a Pontian Greek prince, who was the son King Mithridates VI of Pontus from his concubine and later wife, Stratonice of Pontus. His mother turned over the stronghold of Mithridates at Coenum that had been entrusted to her protection to the Roman forces under Pompey. In revenge, Mithridates had Xiphares killed, leaving his corpse unburied.
