Justus (died on 10 November between 627 and 631) was the fourth archbishop of Canterbury. Pope Gregory the Great sent Justus from Italy to England on a mission to Christianise the Anglo-Saxons from their native paganism; he probably arrived with the second group of missionaries despatched in 601. Justus became the first bishop of Rochester in 604 and signed a letter to the Irish bishops urging the native Celtic church to adopt the Roman method of calculating the date of Easter. He attended a church council in Paris in 614.
