Neoptolemus I of Epirus (Greek: Νεοπτόλεμος Α' Ηπείρου) (370–357 BC) was a Greek king of Epirus and son of Alcetas I, and father of Troas, Alexander I of Epirus and Queen Olympias. He was the maternal grandfather of Alexander the Great and great-grandfather of Pyrrhus of Epirus.[1] He claimed he was a descendant of hero Achilles and King Lycomedes, while Emperor Caracalla claimed that he was a descendant of Neoptolemus I. Olympias was originally known as Polyxena and it is possible that Neoptolemus gave her that name.
