Duke of Grimaldi
Duke of Grimaldi () is a hereditary title in the Peerage of Spain, accompanied by the dignity of Grandee and granted in 1777 by Charles III to Pablo Jerónimo de Grimaldi, who was Prime Minister of Spain as Secretary of State and a member of the House of Grimaldi, the princely family of Monaco.

When the second duke died, the title became vacant for almost a century, until Alfonso XIII rehabilitated it on behalf of María del Rosario Patiño y Losada, the most senior direct descendant of the last titleholder, thus becoming the 3rd Duchess of Grimaldi in 1927.
