Romanus was a 7th-century bishop who served as the second leader of the see of Rochester in England. He was likely a member of the Gregorian mission, which sought to convert the Anglo-Saxons to Christianity. Following the elevation of his predecessor, Justus, to the position of Archbishop of Canterbury, Romanus was consecrated as bishop around 624. His tenure was relatively brief, as he died while traveling to Rome to act as a representative for the archbishop.
