Amphion and Zethus were, in ancient Greek mythology, the twin sons of Zeus by Antiope. They are important characters in one of the two founding myths of the city of Thebes, because they constructed the city's walls. Zethus or Amphion had a daughter who was called Neis (Νηίς), the Neitian gate at Thebes was believed to have derived its name from her.

In Greek mythology, Antiope was the daughter of the Boeotian river god Asopus, according to Homer; in later sources she is called the daughter of the "nocturnal" king Nycteus of Thebes or, in the Cypria, of Lycurgus, but for Homer her site is purely Boeotian. She was the mother of Amphion and Zethus.
