Titus Sextius Lateranus was a Roman senator active in the second century AD. He was ordinary consul in the year 154 as the colleague of Lucius Verus. Lateranus is also known by a more full name, which has been restored in two different ways: Titus Sextius Lateranus M. Vibius Ovel[lius?...] Secundus L. Vol[usius Torquatus?] Vestinus, or Titus Sextius ... M. Vibius Qui[etus?] Secundus L. Vol[usius Torquatus?] Vestinus.
Lateranus was a member of the Roman Republican gens Sextia. He was the son of Titus Sextius Cornelius Africanus, consul in 112, by his wife, a noblewoman from the gens Vibia.
The cursus honorum for Lateranus can be reconstructed from an inscription from Rome. That this inscription attests he was a member of the tresviri monetalis, the most prestigious of the four boards that comprised the vigintiviri, and performed his duties as a quaestor for the Emperor indicates he became a member of the patrician order. His status also explains the absence of any office between quaestor and his consulate except for praetor. At an unknown date he was a member of the sodales Hadrianales, a priesthood dedicated to performing rituals honoring the deified emperor Hadrian. He served as a Proconsul of the Province of Africa in 168/169, considered the apex of a successful senatorial career.
Lateranus was the father of Titus Sextius Magius Lateranus, ordinary consul in 197.
