Luis Ramírez de Lucena (c. 1465 – c. 1530) was a Spanish chess player who published the first extant chess book. He is believed to be the son of humanist writer and diplomat Juan de Lucena.^[1]

Lucena wrote the oldest surviving printed book on chess, Repetición de Amores y Arte de Ajedrez con CL [150] Juegos de Partido ("Repetition of Love and the Art of Playing Chess with 150 Games"), published in Salamanca around 1497.^[2] The book includes analysis of eleven chess openings but also contains many elementary errors that led chess historian H. J. R. Murray to suggest that it was prepared in a hurry.^[3] The book was written when the rules of chess were taking their modern form (see origins of modern chess), and some of the 150 positions in the book are of the old game and some of the new. Fewer than a dozen copies of the book exist.

Commentators have suggested that much of the material was copied from Francesc Vicent's now-lost 1495 work Libre dels jochs partits dels schacs en nombre de 100.^[4]

The Lucena position is named after him, even though it does not appear in his book. (It was first published in 1634 by Alessandro Salvio.) The smothered mate (later named Philidor's legacy) is in the book.^[5]
