Theophilos or Theophilus or Theophilou (813 - 20 January 842) was Byzantine emperor of Armenian origin from 829 to 842. He was the second emperor of the Phrygian dynasty.
Theophilos was the son of the Byzantine Emperor Michael II and his wife of Armenian descent Thekla, and the godson of Emperor Leo V the Armenian. Michael II crowned Theophilos co-emperor in 822, shortly after his own accession. Unlike his father, Theophilos received an extensive education, and showed interest in the arts. On October 2, 829, Theophilos succeeded his father as sole emperor.
Theophilos continued in his predecessors' iconoclast, though without his father's more conciliatory tone, issuing an edict in 832 forbidding the veneration of icons. He also saw himself as the champion of justice, which he served most ostentatiously by executing his father's co-conspirators against Leo V immediately after his accession. His reputation as a judge endured, and in the literary composition Timarion Theophilos is featured as one of the judges in the Netherworld.
