Marcellinus Comes was a Latin chronicler of the sixth century. He spent his life at the court of Constantinople, where he was chancellor to Justinian and obtained various high places in the government. Otherwise little or nothing is known of his life. He died apparently soon after 534. The only surviving work of Marcellinus is his chronicle. It covers the period from 379 to 534.

Chronicon, 474 AD
