Theophilos (Greek: Θεόφιλος; sometimes Latinized or Anglicized as Theophilus; 813 – 20 January 842 AD) was the Byzantine Emperor from 829 until his death in 842. He was the second emperor of the Amorian dynasty and the last emperor to support iconoclasm. Theophilos personally led the armies in his lifelong war against the Arabs, beginning in 831.

Theophilos was the son of the Byzantine Emperor Michael II and his wife 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 from John Hylilas, the grammarian, and was a great admirer of music and art. On 2 October 829, Theophilos succeeded his father as sole emperor.

Theophilos continued in his predecessors' iconoclasm, 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.

At the time of his accession, Theophilos was obliged to wage wars against the Arabs on two fronts. Sicily was once again invaded by the Arabs, who took Palermo after a year-long siege in 831, established the Emirate of Sicily, and gradually continued to expand across the island. The invasion of Anatolia by the Abbasid Caliph Al-Ma'mun in 830 was led by the Emperor himself, but the Byzantines were defeated and lost several fortresses. In 831 Theophilos retaliated by leading a large army into Cilicia and capturing Tarsus. The Emperor returned to Constantinople in triumph, but in the autumn he was defeated in Cappadocia. Another defeat in the same province in 833 forced Theophilos to sue for peace (Theophilos offered 100,000 gold dinars and the return of 7,000 prisoners), which he obtained the next year, after the death of Al-Ma'mun.
