In Greek mythology, Idaea or Idaia (Ancient Greek: Ἰδαία, 'she who comes from Ida' or 'she who lives on Ida') was, by some accounts, the daughter of the Scythian king Dardanus, and the second wife of Phineus, the king of Thrace. Idaea's false accusations against her stepsons were responsible for her husband's misfortunes. She was sent back to Scythia, where she was condemned to death. Other ancient sources give other names for Phineus' second wife, including: Eidothea, sister of Cadmus, and Eurytia.
