Tambeae was a Roman civitas located in the province of Byzacena in Africa Proconsulare. It existed from the Roman era into late antiquity.^[1]

Bishopric

Tambeae must have been of some importance as it was the seat of an ancient Christian diocese which remains today as a titular see of the Roman Catholic Church.^[2][3]

There are five documented bishops of this African diocese.

• Secondiano took part in the council held in Carthage in 256 by St. Cyprian to discuss the question concerning the lapsii.
• Gemellio took part in the council of Cabarsussi, held in 393 by the Maximianists, a dissident sect of the Donatists, and signed the deeds.
• At the Carthage conference of 411, which saw the Catholic and Donatist bishops of Roman Africa gathered together, the town was represented by the Catholic bishop Sopater and the Donatist Faustino.
• Servus Dei intervened at the synod gathered in Carthage by Huneric the Vandal king in 484, after which he was exiled.

Today Tambeae survives as a titular bishop's seat;^[4] the current titular bishop is John Anthony Boissonneau, auxiliary bishop of Toronto.
