Tamalluma is a former Roman city which remains a Latin Catholic titular bishopric

The city was at Telmin, an oasis in present Tunisia, one of many in the Roman province of Byzacena, which were suffragan of the Metropolitan Archbishopric Hadrumetum (Sousse), but faded.^[1][2][3]

The diocese was nominally restored in 1933 as a titular bishopric, of the (lowest) episcopal) rank, with a single incumbent of Archiepiscopal rank.^[4]
