Rudolf (also Rudolph or Rodolf, Italian Rodolfo) was the papal rector of the Duchy of Benevento under Pope Leo IX from 1053 to 1054.
Rudolf was a Swabian captain who led that contingent of forces at the Battle of Civitate. His men were routed by Richard I of Aversa. Rudolf was made rector of Benevento after the pope concluded a treaty with the Normans. Rudolf did not hold his post for very long; the fickle Beneventans recalled their old princes, whom they had once expelled, Pandulf III and Landulf VI.
