Duke of Cardona (Spanish: Duque de Cardona) is a hereditary title in the Peerage of Spain, accompanied by the dignity of Grandee.

The title was granted in 1491 by Ferdinand II to Juan Ramón Folch de Cardona, 5th Count of Cardona, as an elevation to dukedom.

[2][3] It was originally granted as "Viscount of Cardona" (1040-1375) and later elevated to "Count of Cardona" (1375-1491), as a noble title in the 15th century to members of the Catalan family known as "Folch de Cardona".
