Obbi was an ancient city and former diocese in Africa Proconsulare. It is now a Roman Catholic titular see.
Obbi was among the numerous towns in the Roman province of Mauretania Caesariensis which were important enough to become a suffragan bishopric, yet faded completely, even its location in modern Algeria hasn't been identified.
Its only recorded incumbent, Eusabius, attended the Council of Carthage of 484, called by the king Huneric, as one of his Vandal Kingdom's Catholic bishops, like most of those afterwards banished, unlike the schismatic adherents of the heresy Donatism.
The diocese was nominally restored in 1933 as Latin titular bishopric of Obbi (Latin = Curiate Italian) / Obbitan(us) (Latin adjective).
It has had the following incumbents, so far of the fitting Episcopal (lowest) rank:
