Prince Amedeo, Duke of Aosta (Amedeo Umberto Costantino Giorgio Paolo Elena Maria Fiorenzo Zvonimir di Savoia; born 27 September 1943) is a claimant to the headship of the House of Savoy, the family which ruled Italy from 1861 to 1946.
Until 7 July 2006, Amedeo was styled Duke of Aosta; on that date he declared himself Duke of Savoy, a title that is disputed between him and his third cousin, Vittorio Emanuele, Prince of Naples.
In the event that Vittorio Emanuele and his son will fail to produce any legitimate male heirs, their claim to the Italian throne will pass on to Amedeo and his male-line descendants.
