Antiochus Chuzon (floruit 429-438), called "the Elder" to distinguish him from his nephew, was a high official of the Eastern Roman Empire, praetorian prefect of the East and consul, who was a key figure in the compilation of the Codex Theodosianus.
Later he was appointed praetorian prefect of the East, an office he held between 430 and 431. During his tenure, he exchanged letters with Theodoret, organised with Nestorius his return to the East through Asia Minor and Pontus, and rebuilt the city walls of Antioch.
In 431 he was appointed consul by the Eastern court, with Anicius Auchenius Bassus as Western colleague.
In 435 he was appointed member of the second commission for the formulation of the Codex Theodosianus. When the Codex was issued in 438, Antiochus was listed among its formulators.
He died between 438 and 444.
