Ceramus or Keramos (Greek: Κέραμος) was a city on the north coast of the Ceramic Gulf—named after this city—in Caria, in southwest Asia Minor; its ruins can be found outside the modern village of Ören, Muğla Province, Turkey.
Ceramus, initially subjected to Stratonicea, afterwards autonomous, was a member of the Athenian League and was one of the chief cities of the Chrysaorian League (Bulletin de corresp. hellén., IX, 468). In ancient times, it probably had a temple of Zeus Chrysaoreus. In Roman times, it coined its own money.
Ceramus is mentioned in the Notitiae Episcopatuum until the 12th or 13th century as a bishopric suffragan to Aphrodisias, or Stauropolis. Three bishops are known: Spudasius, who attended the First Council of Ephesus in 431; Maurianus, who attended the Council of Nicaea in 787; and Symeon, who attended the council in Constantinople that reinstated Photius in 879.
