Pope Victor III (c. 1026 – 16 September 1087), born Dauferio, was Pope from 24 May 1086 to his death in 1087. He was the successor of Pope Gregory VII, yet his pontificate is far less impressive in history than his time as Desiderius, the great Abbot of Montecassino.His failing health was the factor that made him so reluctant to accept his pontifical election and his health was so poor that he fell to illness during his papal coronation.
