Korba (Tunisian Arabic: قربة qorbāⓘ), ancient Curubis, is a town in Tunisia on the eastern shore of the Cap Bon.

[3][4] In the years after the civil war the town was made a Roman colony, colonia Iulia Curubis (Pliny the Elder refers to it as libera, "free"), perhaps as part of Julius Caesar's attempt to rid his army of older soldiers and at the same time hold Africa against Pompeian forces.

[5] In the year AD 257, the Carthaginian bishop Cyprian was exiled there; his biographer Pontius, who accompanied him into exile, praises the place (12): "provisum esse divinitus … apricum et conpetentem locum, hospitium pro voluntate secretum et quidquid apponi eis ante promissum est, qui regnum et iustitiam dei quaerunt."

[7] A recent account of the life in Korba may be found in Mounira Khemir's narrative "Un coin du carré bleu"[8] By the year 411, Curubis, like many African towns, had its own bishop.

The bishopric survived through the Arian Vandal and Orthodox Byzantine empires, only ceasing to function with the Muslim conquest of the Maghreb.
