Luis Jesús Fernández de Córdoba y Salabert, 17th Duke of Medinaceli, GE (16 January 1880 – 13 July 1956), was a Spanish nobleman and trophy hunter.

He was born posthumously to his father, who had died in a hunting accident some months earlier and as such he assumed the historical titles of the House of Medinaceli from birth.

His mother, who would become the 11th Duchess of Ciudad Real in her own right, remarried the politician Mariano Fernández de Henestrosa, 1st Duke of Santo Mauro, in 1884.

Considered one of the main exponents of big-game hunting in Europe, the duke made expeditions to British East Africa (1908-1909) and the North Pole (1910, 1921).

After suffering a myocardial infarction, Luis Fernández de Córdoba died on July 13, 1956, in the now disappeared Palace of the Duke of Uceda in Madrid.
