Amyntas III () was king of the ancient Greek kingdom of Macedonia from 393/2 to 388/7 BC and again from 387/6 to 370 BC. He was a member of the Argead dynasty through his father Arrhidaeus, a son of Amyntas, one of the sons of Alexander I. His most famous son is Philip II, father of Alexander the Great. Family Polygamy was used by Macedonian kings both before and after Amyntas to secure marriage alliances and produce enough heirs to offset losses from intra-dynastic conflict. Consequently, Amyntas took two wives: Eurydice and Gygaea. He first married the former, daughter of the Lyncestian-Illyrian Sirras, by 390 BC and possibly in the aftermath of an Illyrian invasion. Through Eurydice, Amyntas had three sons, all of whom became kings of Macedonia one after the other, and a daughter: Alexander II, Perdiccas III, Philip II, and Eurynoe. The Roman historian Justin relates several, possibly apocryphal, stories about Eurydice and Eurynoe. He claims that Eurynoe prevented her mother and her lover (unnamed, but likely Ptolemy of Aloros) from assassinating Amyntas late in his reign by revealing the plan to her father. However, Eurynoe is not referred to by name in any other source and, moreover, is unlikely to have known the details of this supposedly secret plot. According to Justin, Amyntas spared Eurydice because they shared children, but that she would later help murder Alexander and Perdiccas in order to place Ptolemy on the throne. Alexander was in fact killed by friends of Ptolemy at a festival in 368, but the extent to which Eurydice knew of or participated in this plot is opaque. Perdiccas, on the other hand, assassinated Ptolemy in 365 only to be killed in battle by the Illyrians in 359. Amyntas most likely married Gygaea soon after marrying Eurydice, because Gygaea's children made no attempt to claim the throne before the 350s, implying that they were younger than Eurydice's children. Additionally, both Diodorus and Justin call Alexander II the eldest son of Amyntas. Through Gygaea, Amyntas had three more sons: Archelaus, Arrhidaeus, and Menelaus. Unlike Eurydice's children, none of Gygaea's sons ascended to the throne and were all killed by their half-brother Philip II.
