Pompeius (Greek: Πομπήιος, died 532) was a politician of the Eastern Roman Empire and nephew of the Emperor Anastasius I (reigned 491–518). His family gained political prominence with the accession of Anastasius. Pompeius was consul in 501, and was elevated to the patricianate, probably by Anastasius. He held military office, serving in the Iberian War. He married a woman named Anastasia, and had at least one son. In 532, Pompeius' brother Hypatius was acclaimed emperor by the rioters during the Nika riots; after the riots were put down, both Hypatius and Pompeius were executed.
