Pope Pelagius II (520 – 7 February 590) was Pope from 26 November 579 to his death in 590.

Born in 520, Pelagius was a native of Rome, but probably of Ostrogothic descent, as his father's name was Winigild. Pelagius appealed for help from Emperor Maurice against the Lombards, but the Byzantines were of little help, forcing Pelagius to "buy" a truce and turn to the Franks, who invaded Italy, but left after being bribed by the Lombards.
