Baron of Santa Pau (Spanish: Barón de Santa Pau) is a hereditary title in the Spanish nobility created in Catalonia on an unknown date, though believed to have been made before 1070, as at that time, in Girona, there are records of a knight named Almérico I de Santa Pau as the lord of this barony,[1] being the first person recorded as such.

Sentence was given in 1445, confirmed in 1446 and 1449, in favour of Juana, and in 1456, the curia of Besalú put the barony up for sale.

The Royal Audience of Catalonia ruled in favour of his son, Félix I (then 18th Baron), on 1 June 1730, after his father's death.

[6] After almost 4 years of legal battles, Ruiz de la Prada, through judicial sentence, was granted both titles.

The heir apparent is Tristán Jerónimo Ramírez Ruiz de la Prada (born 1987), eldest son of the 29th Baroness.
