Artabasdos Emperor (usurper) of the Byzantine Empire from 742 to 743.
Artabasdos was a Byzantine general of Armenian descent who seized the throne from June 741 or 742 until November 743. His reign constitutes a usurpation against Constantine V, who had retained control of several themes in Asia Minor.

Artabasdos abandoned his predecessor's religious policy of Iconoclasm and restored Orthodoxy with some support, including that of Pope Zacharias. Soon after his accession, Artabasdus crowned his wife Anna as Augusta and his son Nikephoros as co-emperor, while putting his other son Niketas in charge of the Armeniac theme. But while Artabasdus could rely also on the support of the themes of Thrace and Opsikion, Constantine secured for himself the support of the Anatolic and Thracesian themes.

The inevitable clash came in May 743, when Artabasdus led the offensive against Constantine but was defeated. Later the same year Constantine defeated Niketas, and on November 2, 743 Artabasdus' reign came to an end as Constantine V entered Constantinople and apprehended his rival. Artabasdus and his sons were publicly blinded and relegated to the monastery of Chora on the outskirts of Constantinople. The date of his death is unknown.
