Carlos José Gutiérrez de los Ríos y Rohan-Chabot, 6th Count of Fernán Núñez (11 July 1742 – 23 February 1795) was a Spanish soldier and Diplomat whose military career spanned over two decades.

His mother was the granddaughter of Louis, Duke of Rohan and thus, through his matrilineal line, he was a descendant of Charles VII of France, Henry III of England and various other monarchs.

[1] After both of his parents had died, King Ferdinand VI took him under his protection and paid for his studies at the Royal Seminary of Nobles in Madrid.

Although he had planned for further travelling, after hearing of the Spanish preparations against the Barbary, he thought that he should return to the army and serve the King.

He returned to the position of Colonel of the King's Inmemorial Regiment and was awarded the Grand Cross of Charles III.
