Hegemon, an Athenian orator of the time of Demosthenes, and one of those who were induced by the bribes of Philip to support the Macedonian party. He was capitally accused by Aristogeiton, and at last shared the fate of Phocion. According to Syrianus, he was one of those orators who attained to eminence by practice, without having studied the art of rhetoric. (Dem. adv. Aristog. i. p. 784; Pseud. Aeschin. Epist. xii.; Liban. i. p. 471, b.; Harpocrat. s. v.; Plut. Phocion, 33, 35.)
