Tiberius Claudius Julianus was a Roman senator and literary figure who held several offices in the imperial service during the later second century AD. He was suffect consul during the nundinium of September-October 154 with Sextus Calpurnius Agricola as his colleague. Julianus came from a well-to-do family in Roman Asia Minor. His grandmother, Julia Quintilia Isauria, was the daughter of Tiberius Julius Celsus Polemaeanus, consul in 92.
