Julius Antiochus (3rd century AD - 4th century AD) was a 4th-century Roman official, active during the reign of the emperor Constantine I (r. 306–337).
According to laws XV 14.3 (of 6 January 313), I 2.1 (of 30 December 314) and II 10.1+2 (of 1 November 319) of the Codex Theodosianus, he served in this period as praefectus vigilum.
[1] According to Ilkka Syvanne, it may be possible to associate him with the general of the same name who served in Armenia under Constantius II (r.
337–361).
