The House of Ávalos (also mentioned in sources as Dávalos, Ávalos, Ábalos, de Ávalos, Avalo, Abalón) is an aristocratic family of Spanish origin that also branched out in Italy starting from the 15th century. The Italian branch of the family was the owner of numerous fiefs in the Kingdom of Naples until the abolition of feudalism and in the Duchy of Milan, including within it several notable figures in the political, military and ecclesiastical fields.

The d'Avalos family also had, in the person of Cesare Michelangelo d'Avalos, the title of Prince of the Holy Roman Empire and the right to mint coins. The family held the title (although it became substantially honorific in the mid-16th century) of Grand Chamberlain or Camerlengo, one of the Seven Great Offices of the Kingdom of Naples, for 195 years.
