Caloe was a Byzantine town in Asia Minor, the original see is mentioned as Kaloe, and Keloue in inscriptions of the third century, Kalose in Hierocles's Synecdemos (660); as Kalloe, Kaloe, and Kolone in Parthey's Notitiæ episcopatuum, where it figures from the sixth to the twelfth or thirteenth century.
There was in Lydia a Lake Koloe, near which the tombs of Lydian kings and the temple of Artemis Koloene stood. According to Lequien, the titular see took its name from this locality; but his view is inconsistent with the position assigned to Caloe by the Notitiæ episcopatuum as a suffragan see of Ephesus. It remains a titular see of the Catholic Church to this day.
