Pyrrhus or Pyrrhos (319-272 BC) was a Greek general of the Hellenistic era. He was king of the Greek tribe of Molossians, of the royal Aeacid house (from ca. 297 BC), and later he became King of Epirus (306-302, 297-272 BC) and Macedon (288-284, 273-272 BC). He was one of the strongest opponents of early Rome. Some of his battles, though successful, cost him heavy losses, from which the term "Pyrrhic victory" was coined. He is the subject of one of Plutarch's Parallel Lives.
