Bordj-Bou-Djadi is an archaeological site and former Catholic diocese located on the outskirts of Tunis, Tunisia. The area is situated near Ucres, at 36.901123n, 9.97083e. It is now a Latin Catholic titular see.

The stone ruins at Bordj-Bou-Djadi have been tentatively identified with the Roman–Berber town of Ucres, a civitas of the Roman province of Africa Proconsularis, important enough to become one of the many suffragans of Carthage, the Metropolitan at its capital.^[1][2] It flourished from 30BC until around 640AD.

Several of its bishops are known from antiquity:^[3]

• Vitalis fl. 314, participant at the Council of Arles in 314 which condemned Donatism as heresy.
• Victor fl. 404, whose son left an epitaph in Rome
• Maximinus participated in the Council of Carthage in 411 with other Catholic and Donatist bishops, including his schismatic counterpart Vitalis, 411
• Quoduultdeus fl. 416–429, participated in the Council of Carthage in 419 on appeals to Rome
• Exitiosus fl. 484, participated in the Council of Carthage called in 484 by king Huneric of the Vandal Kingdom, after which he was exiled, like most Catholic bishops.

The ancient diocese was nominally restored in 1933 as Latin titular bishopric of the Roman Catholic Church,^[4] as Ucres (Latin and Curiate Italian) / Ucren(sis) (Latin adjective)/
