Thunigaba was an ancient Roman(-Berber?)
town in Roman Africa.
The city was one of many in the Late Roman province of Africa proconsularis which were important enough to become a suffragan see of the primatial Metropolitan of Carthage, but later faded.
Its ruins are near modern Henchir-Aïn-Laabed, in present Tunisia.
In 1933, the diocese was nominally restored as a Latin titular bishopric of the lowest (episcopal) rank.
