Octaba was an ancient Roman–Berber city in the province of Africa Proconsularis and Byzacena in late antiquity.
[1] Its exact location is now lost, but it was in the Sahel region of Tunisia.
In 484AD the town's Catholic bishop, Sabinico, attended a synod in Carthage called by the Arian king Huneric, the Vandal.
Today Octabia survives only as a titular bishopric of the Roman Catholic Church.
