Sicca Veneria (episcopal see)

The Diocese of Sicca Veneria was an episcopal see of Africa Proconsularis, and was a suffragan of the bishops of Carthage. The cathedra of the bishopric was in the Roman colonia (highest ranking city) of Colonia Julia Veneria Cirta Nova Iulia. The bishopric was founded in early Christianity; it ceased to function sometime after the Muslim conquest of the Maghreb.

It exists today as a titular see of the Roman Catholic Church. The current bishop is Lajos Varga of Hungary.

Remains of the bishopric included ruins at El Kef of a cathedral, baptistry, Christian burials, and numerous Christian inscriptions.
