Tambeae was a Roman civitas located in the province of Byzacena in Africa Proconsulare.
It existed from the Roman era into late antiquity.
[1] 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.
Today Tambeae survives as a titular bishop's seat;[4] the current titular bishop is John Anthony Boissonneau, auxiliary bishop of Toronto.
