Quiza, which Pliny the Elder called Quiza Xenitana, was a minor city or colony in Roman Africa, located in the late Roman province of Mauretania Caesariensis, William Smith identified it with Giza near Oran, Algeria. More recent investigations have identified it with present-day El-Benian on the coast road between Mostaga and Dara.
In his Natural History, 4.2.3., Pliny the Elder: writes: "Next to this is Quiza Xenitana, a town founded by strangers"; a remark explained because the word Xenitana is derived from Greek ξένος, "a stranger", as explained also by Victor Vitensis. The town is mentioned also by Pliny elsewhere (5.2), by Ptolemy, and by Pomponius Mela.
At the Conference of Carthage in 411, which brought together Catholic and Donatist bishops, Quiza was represented by the Catholic Priscus, who had no Donatist counterpart. He is mentioned also in a letter of Saint Augustine to Pope Celestine I. Tiberianus of Quiza was one of the Catholic bishops whom the Arian Vandal kind Huneric summoned to Carthage in 484 and then exiled. In addition, the name of a Bishop Vitalianus appears in the mosaic pavement of the excavated basilica of Quiza.
