Caesaropolis is a Byzantine city and a Catholic titular see on the coast of eastern Macedonia.
It was founded in 836 by the Caesar Alexios Mosele to consolidate Byzantine control over the Slavic tribes of the area.
It is mentioned in Heinrich Gelzer's Nova Tactica (1717) and in Parthey's Notitiae episcopatuum, III (c. 1170-1179) and X (twelfth or thirteenth century), as a suffragan of Philippi in Macedonia. Lequien (II, 65) speaks of the see, but mentions no bishop. Manuscript notes give the names of two titulars, Meletius, who was alive in April, 1329, and Gabriel, in November, 1378.
