Thesmophoriazusae (Greek: Θεσμοφοριάζουσαι) or Women at the Thesmophoria is a comedy by Aristophanes, first produced at Athens in 411 BC, probably at the Dionysia. As with Lysistrata, thought to have been produced at the Lenaea in the same year, gender forms a significant theme of the work, which is set during the Thesmophoria, a festival attended solely by women.
The tragic poet Euripides features as a central character. who learns that the festival-goers intend to kill him because of the negative portrayal of women in his work. After failing to persuade his fellow tragedian Agathon to infiltrate the festival on his behalf, Euripides sends an elderly relative instead. After the infiltrator is discovered, attempts to rescue him devolve into a series of parodies of Euripides' plays.
