Gratianopolis was one of towns named after the Roman emperor Gratian (367 to 383). It is only known from mentions in church council minutes. Its history, location and present condition are unknown.

No later then 1652, the diocese has been nominally restored as a Latin titular bishopric of Gratianopolis (Latin) / Grazianopoli (Curiate Italian) / Gratianopolitan(us) (Latin adjective).

It has had the following incumbents, so far of the fitting Episcopal (lowest) rank :
