Mattiana was a Roman-Berber civitas in the province of Africa Proconsularis.
The locale existed during late antiquity, and was situated in northern Tunisia.
[1] In antiquity, the town was also the seat of a Catholic bishopric,[2][3] suffragan of the Archdiocese of Carthage.
The historical sources mention only one known bishop, Marcellus, who took part in the Council of Carthage of 646.
Today Mattiana survives as a titular bishopric[4] of the Roman Catholic Church and the current bishop is Carlos Alberto Salcedo Ojeda of Huancayo, [5] who replaced Edmar Peron in 2016.
