Thimida Regia was an ancient settlement in the Roman province of Africa Proconsularis (later part of Byzacena) whose exact location is not definitively identified but is generally thought to lie within the boundaries of present‑day Tunisia. The name appears in historical and ecclesiastical sources as the seat of a Christian bishopric during the Roman and early Byzantine periods.
History
Thimida Regia is recorded in the Notitia Provinciarum et Civitatum Africae, a late Roman‑Byzantine list of cities and episcopal sees, indicating that it held the status of a civitas (city) within the provincial hierarchy. The appellation Regia (Latin for “royal”) distinguishes it from other settlements named Thimida, suggesting a particular administrative or founding significance, though the precise reason for this designation is not documented in surviving sources.
Location
The site of Thimida Regia has not been conclusively located by modern archaeology. Scholarly consensus places it somewhere in central or southern Tunisia, but no definitive ruins or inscriptions have been securely linked to the name. Consequently, the coordinates and modern toponym for the ancient town remain uncertain.
Ecclesiastical significance
During the spread of Christianity in North Africa, Thimida Regia became the seat of a bishopric subordinate to the Metropolitan Archbishop of Carthage. Several bishops of Thimida Regia are listed in the acta of the Councils of Carthage (e.g., the council of 411 CE, which addressed the Donatist controversy). The diocese ceased to function effectively after the Arab conquest of the Maghreb in the 7th century, but the Catholic Church retained the title as a titular see. It appears in the Annuario Pontificio as a suppressed diocese whose title may be assigned to auxiliary bishops.
Modern status
In contemporary ecclesiastical practice, the titular see of Thimida Regia is occasionally assigned to bishops serving in non‑diocesan capacities. No active parish or diocesan structures exist at the presumed location, reflecting the transformation of the region’s religious landscape over the intervening centuries.

Note: While the existence of Thimida Regia as a Roman‑era city and ecclesiastical jurisdiction is documented, many details—particularly its precise archaeological location and the origins of its epithet “Regia”—remain uncertain.
