Ferdinand de la Cerda (1255–1275) was the heir apparent to the Crown of Castile as the eldest son of Alfonso X and Violant of Aragon. His nickname, de la Cerda, means "of the bristle" in Spanish, a reference to being born with a full head of hair.

In November 1268 he married Blanche, the daughter of King Louis IX of France. They had two sons:

Ferdinand predeceased his father in 1275 at Ciudad Real from wounds received at the Battle of Écija. His sons did not inherit the throne of their grandfather, since their uncle Sancho usurped the throne.
