Saint Eugenius II (died 13 November 657), sometimes called Eugenius the Younger as the successor of Eugenius I, was Archbishop of Toledo from 647 until his death.
He is called Eugenius secundus (Eugene the second) in the biography of Archbishop Julian of Toledo by a certain Felix, but in later histories he is sometimes numbered Eugenius III when a legendary martyr and first bishop of Toledo is included.[1]
