Siccenna was a Roman Era town and episcopal see in the Roman province of Africa Proconsularis in what is today northern Tunisia, which is now a Latin Catholic titular bishopric.

History

Siccenna was also the seat of an ancient episcopal see,^[1] one of many suffragans of the Metropolitan Archdiocese of Carthage.^[2]

The only known Roman era bishop of this diocese was the African Donatist Ciprian, who participated in the Council of Carthage (411), the city at that time had no Catholic bishops.
