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.

Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of ancient Greek folklore, today absorbed alongside Roman mythology into the broader designation of classical mythology. These stories concern the ancient Greek religion's view of the origin and nature of the world; the lives and activities of deities, heroes, and mythological creatures; and the origins and significance of the ancient Greeks' cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself.
