Lete (Greek: Λητή, modern Liti) was an ancient city in Mygdonia, Macedon and Roman Catholic titular see in Macedonia (Roman province). As Liti, it is a town in the northern suburbs of Thessaloniki, Central Macedonia, Greece. It was the seat of the former municipality of Mygdonia.
Lete is known by its coins and inscriptions, mentioned in Ptolemy (III, xiii), the Pliny the Younger (IV, x, 17), Harpocration, Stephanus Byzantius and Suidas in Antiquity and in the Middle Ages in Nicephorus Bryennius (IV, xix). The spelling "Lite" is incorrect and comes from iotacism.
Lete appears in some Notitiæ episcopatuum of a late period as suffragan of the Archbishopric of Thessalonica, later united to the See of Rentina. Lete and Rentina even had Greek (Orthodox) bishops until the eighteenth century.
