This is a list of dukes and princes of Benevento during the Duchy of Benevento between 577–774, the Principality of Benevento between 774–1081, and the Napoleonic creation Principality of Benevento (Napoleonic) between 1806-1815.
In 1050, the Lombard co-princes were expelled from the city by the discontented citizenry.
In 1053, the Normans who had occupied the duchy itself since 1047 (when the Emperor Henry III gave permission to Humphrey of Hauteville) ceded it to the Pope with whom they had recently made a truce.
The pope appointed his own rector, but the citizens invited the old princes back and, by 1055, they were ruling again; as vassals of the pope, however.
Guiscard returned it to the Pope, but no new Beneventan prince or dukes were named until the 19th century.
