Maximiana in Numidia was an Ancient city and bishopric in Roman Africa and remains a Latin Catholic titular see.

Its presumed location are the ruins of Mexmeia, in present Algeria.

Maximiana was important enough in the Roman province of Numidia to become one of its Metropolitan's many suffragan bishoprics, but was to fade.

The diocese was nominally restored in 1925 as the titular bishopric of Maximiana, renamed in 1933 Maximiana in Numidia.
