Lamia (; Ancient Greek: Λάμια, romanized: Lámia), in ancient Greek mythology, was a child-eating monster and, in later tradition, was regarded as a type of night-haunting spirit or "daimon". In the earliest myths, Lamia was a beautiful queen of ancient Libya who had an affair with Zeus and gave birth to his children. Upon learning of this, Zeus's wife Hera robbed Lamia of her children, either by kidnapping them and hiding them away, killing them outright, or forcing Lamia to kill them. The loss of her children drove Lamia insane, and she began hunting and devouring others' children.
