Luis Suárez Fernández (25 June 1924 – 15 December 2024) was a Spanish historian, originally a medievalist, who has extended his studies to include modern and recent history.
In 1975, Suárez took up the chair of medieval history at the recently inaugurated Autonomous University of Madrid.
That same year he became director of the Escuela Española en Roma de Arqueología e Historia [es] of CSIC, a Spanish cultural society in Rome.
He authored the entry for Francisco Franco in the 2011 Diccionario Biográfico Español, published by the Real Academia de la Historia, which has been denounced by historians as being Francoist propaganda.
He was elected to medalla nº 4 of the Real Academia de la Historia on 7 May 1993; he took up his seat on 23 January 1994.
