Mauriana was an ancient city and bishopric in Roman North Africa, which remains a Latin Church titular see of the Catholic Church.

History 
Mauriana was among the many towns in the Roman province of Mauretania Caesariensis which were important enough to become a suffragan diocese, in the papal sway, but destined to fade so completely (at the 7th century advent of Islam?) that its present location in modern Algeria hasn't even been established.

Its earliest recorded bishop may have been Lucianus, who assisted, according to Morcelli, at a council in Rome in 337; Mesnage believes that geographically implausible and suggests his see may rather have been Mariana, Corsica.

Mauriana's only historically sure incumbent was Secondus, participant in the Council called at Carthage in 484 by king Huneric of the Vandal Kingdom, after which he was exiled, like most Catholic participants, unlike their Donatist heretic counterparts.
