Hypsipyle (Ancient Greek: Ὑψιπύλη) is a partially preserved tragedy by Euripides, about the legend of queen Hypsipyle of Lemnos, daughter of King Thoas. It was one of his last and most elaborate plays. It was performed c. 411–407, along with The Phoenician Women which survives in full, and the lost Antiope. Originally only known from a few fragments, knowledge of the play was greatly expanded with the discovery of Oxyrhynchus Papyrus 852 in 1905, and its publication by Grenfell and Hunt in 1908. Of his lost plays, it is the one with the most extensive fragments.
