Tribonian or Tribonianos (Τριβωνιανός [trivonia'nos], c. 485?–542) was a notable Roman jurist and advisor, who during the reign of the Emperor Justinian I, supervised the revision of the legal code of the Roman Empire.
Tribonian was born in Side, in Pamphylia, around the year 500. He was well educated and practiced law before the court of the praetorian prefect. Justinian made Tribonian "magister officiorum" (Master of Offices), although it is not clear when, and then appointed him quaestor (Minister of Justice) in September 529.
