Duchess of Palma de Mallorca was a substantive title in the Peerage of Spain.

The title takes its name from the city of Palma de Mallorca, in the Balearic Islands.

The royal dukdom was granted on 26 September 1997 by King Juan Carlos I to his younger daughter, Infanta Cristina, on the occasion of her forthcoming marriage to Iñaki Urdangarin.

That same year, the Duchess and the Duke were granted the Golden Medal of the Balearic Islands.

[1] In 2013, the City Council renamed the street to its original name[2] and, in 2018, the regional government of the islands revoked the Golden Medal to Urdangarin.
