In Greek mythology, Cleoboea (/ˌkliːəˈbiːə/; Ancient Greek: Κλεόβοια, romanized: Kleóboia, lit. 'renowned cattle'), also called Philaechme (Ancient Greek: Φίλαιχμη, romanized: Phílaikhmē), is the wife of Phobius and queen consort of Miletus who falls desperately in love with Antheus, a royal hostage of their court, an infatuation that leads them both to their doom. Cleoboea's myth is known thanks to the works of Hellenistic and Roman-era Greek grammarian Parthenius of Nicaea, who attributes the story to Aristotle and authors of the Milesian tales.
