Appian of Alexandria (/ˈæpiən/; Ancient Greek: Ἀππιανὸς Ἀλεξανδρεύς, romanized: Appianòs Alexandreús; Latin: Appianus Alexandrinus; c. 95 – c. AD 165) was a Greek historian with Roman citizenship who prospered during the reigns of the Roman Emperors Trajan, Hadrian, and Antoninus Pius.
He was born c. 95 in Alexandria. After holding the senior offices in the province of Aegyptus (Egypt), he went to Rome c. 120, where he practiced as an advocate, pleading cases before the emperors (probably as advocatus fisci, an important official of the imperial treasury). It was in 147 at the earliest that he was appointed to the office of procurator, probably in Egypt, on the recommendation of his friend Marcus Cornelius Fronto, an influential rhetorician and advocate. Because the position of procurator was open only to members of the equestrian order (the "knightly" class), his possession of this office tells us about Appian's family background.
