Tigava was an ancient Roman-Berber town and bishopric in Roman Africa, which remains a Latin Catholic titular see.
It corresponds with the modern locality of El-Kherba in Algeria.
Tigava was one of many cties in the Roman province of Mauretania Caesariensis which were important enough to become a suffragan of the Metropolitan Archbishopric in its capital Caesarea Mauretaniae (modern Cherchell), but like most faded.
Tigava's diocese is included in the Catholic Church's list of titular bishoprics since it was nominally restored in 1933.
It has had the following incumbents, so far of the fitting Episcopal (lowest) rank :
