Anicius Olybrius (died 22 October or 2 November 472) was Roman emperor from July 472 until his death later that same year; his rule as augustus in the western Roman Empire was not recognised as legitimate by the ruling augustus in the eastern Roman Empire, Leo I (r. 457–474). He was in reality a puppet ruler raised to power by Ricimer, the magister militum of Germanic descent, and was mainly interested in religion, while the actual power was held by Ricimer and his nephew Gundobad.
