Duke of Cadaval is a title of Portuguese nobility. It was created on 26 April 1648 by King John IV of Portugal for his distant cousin, Dom Nuno Álvares Pereira de Melo (1638–1725), who was already 4th Marquis of Ferreira and 5th Count of Tentúgal.
The Dukes of Cadaval trace their origins to Dom Álvaro of Braganza, Lord of Tentúgal, Póvoa, Buarcos and Cadaval, fourth son of Dom Ferdinand I, 2nd Duke of Braganza. Dom Álvaro married Dona Filipa de Melo, the rich daughter and heiress of Rodrigo Afonso de Melo, 1st Count of Olivença.
