Olympias (Greek: Ὀλυμπιάς, ca. 375–316 BC) was a Greek princess of Epirus, daughter of king Neoptolemus I of Epirus, the fourth wife of the king of Macedonia, Philip II, and mother of Alexander the Great. She was a devout member of the orgiastic snake-worshiping cult of Dionysus, and it is suggested by the 1st century AD biographer, Plutarch, that she may have slept with snakes.
