Amphitryon, in Greek mythology, was a son of Alcaeus, king of Tiryns in Argolis. His mother was named either Astydameia, the daughter of Pelops and Hippodamia, or Laonome, daughter of Guneus, or else Hipponome, daughter of Menoeceus. Amphitryon was the brother of Anaxo, and Perimede, wife of Licymnius. He was a husband of Alcmene, Electryon's daughter, and stepfather of the Greek hero Heracles.

Frontispiece of the 1682 edition of Molière's highly successful comedy Amphitryon, based on a Plautine comic treatment of the myth of the eponymous hero: the gods Jupiter (Zeus), disguised as Amphitryon and mounted upon an eagle, and Mercury (Hermes) descend from Olympus to meddle in the affairs of the play’s human characters.
In Greek mythology, Alcmene or Alcmena was the wife of Amphitryon, by whom she bore two children, Iphicles and Laonome. She is best known as the mother of Heracles, whose father was the god Zeus. Alcmene was also referred to as Electryone, a patronymic name as a daughter of Electryon.
