Hypsipyle is a character from Greek mythology, known primarily for her role in the story of the Argonauts. She was the daughter of Thoas, the king of Lemnos, and became the queen of Lemnos after the women of the island killed their husbands. In the myth, Hypsipyle saved her father from death and later fell in love with Jason, one of the Argonauts. She bore him two sons, Euneus and Thoas, but their relationship was complicated by Jason's quest for the Golden Fleece and his eventual marriage to Medea.
