Giovanni Vincenzo was a tenth-century archbishop of Ravenna who served the see from 983 until 998. Born in Ravenna to a distinguished Lombard family, he previously worked at the cathedral in Pavia and spent time living as a hermit. He is notably remembered for his role in the coronation of the young King Otto III in Aachen, an event where he represented Italy, a unique occurrence within the history of the Holy Roman Empire.
