Pope Theodore II (Latin: Theodorus II; 840 – December 897) was the bishop of Rome and ruler of the Papal States for twenty days in December 897. His short reign occurred during a period of partisan strife in the Catholic Church, which was entangled with a period of violence and disorder in central Italy. His main act as pope was to annul the recent Cadaver Synod, therefore reinstating the acts and ordinations of Pope Formosus, which had themselves been annulled by Pope Stephen VI. He also had the body of Formosus recovered from the river Tiber and reburied with honour. He died in office in late December 897.
