Leosthenes (Ancient Greek: Λεωσθένης Λεωσθένους Κεφαλῆθεν, romanized: Leōsthenēs Leōsthenous Kephalēthen; died 323 BC) was an Athenian who was commander of the combined Greek army in the Lamian War. Leosthenes was the son of his namesake father Leosthenes who had suffered exile in 362/1 BC and who had fled to the court of Philip II.[1][2] It is unknown by what means he had obtained the high reputation he had when he first makes his appearance in history. It has been inferred from a passage in Strabo[3], that he had first served under Alexander the Great in Asia; but it now seems certain that this is a mistake, and rather the reference should have been to Leonnatus.
