Nemea is an ancient site in the northeastern part of the Peloponnese, in Greece. Formerly part of the territory of Cleonae in ancient Argolis, it is today situated in the regional unit of Corinthia. The small village of Archaia Nemea is immediately southwest of the archaeological site, while the new town of Nemea lies to the west.

In Greek mythology, Hypsipyle was a queen of Lemnos, and the daughter of King Thoas of Lemnos, and the granddaughter of Dionysus and Ariadne. When the women of Lemnos killed all the males on the island, Hypsipyle saved her father Thoas. She ruled Lemnos when the Argonauts visited the island, and had two sons by Jason, the leader of the Argonauts. Later the women of Lemnos discovered that Thoas had been saved by Hypsipyle and she was sold as a slave to Lycurgus, the king of Nemea, where she became the nurse of the king's infant son Opheltes, who was killed by a serpent while in her care. She is eventually freed from her servitude by her sons.
