Hilta is an ancient city and bishopric in modern Tunisia. It is now a Latin Catholic diocese.
Hilta was important enough in the Roman province of Africa Proconsularis to become a suffragan bishopric of its capital Carthage's Metropolitan Archbishop, but later faded, presumably under Islam.
The diocese was nominally restored in 1933 as a Latin Catholic titular bishopric.
