Ubaza was an ancient city and bishopric in Roman North Africa, which remains a Latin titular see.
History
Ubaza was among the many towns in the Roman province of Numidia that were important enough to become a suffragan bishopric, but faded. Its present location is in modern Terrebaza, Algeria.
Its only recorded residential bishops both attended the council called in 484 at Carthage by Huneric of the Vandal Kingdom :
- the Catholic Victor, banished afterwards
- the Donastist heretic Secondinus.
Titular see
