Blaundus (Ancient Greek: Βλαῦνδος) was a Greek city founded during the Hellenistic period[1][2] in Asia Minor, presently Anatolia (Asian Turkey), and is now a Latin Catholic titular bishopric.

Its ruins are in Sülümenli (formerly Süleimanli), near Ulubey (formerly Göbek) in the Uşak Province of modern Turkey.

Greek coins have been discovered which write the city name as Mlaundus.

[3] Recent findings of cylinder-seals in archaeological excavation point towards the conclusion that there was a settlement already stablished at the beginning of the 2nd millennium BC, belonging to the Assyrian trade colony period.

[4] In the Roman and Byzantine eras, the city was the seat of a bishopric, a suffragan of the Metropolitan Archdiocese of Sardes.
