Martí de Riquer i Morera, 8th Count of Casa Dávalos (Catalan pronunciation: [mərˈti ðə riˈke j muˈɾeɾə], Spanish: Martín de Riquer y Morera) (3 May 1914 – 17 September 2013) was a Spanish–Catalan literary historian and Romance philologist, a recognised international authority in the field. His writing career lasted from 1934 to 2004. He was also a nobleman and Grandee of Spain.
Riquer was born in Barcelona in 1914, the grandson of Alexandre de Riquer i Ynglada, from whom he rehabilitated the noble title Count of Casa Dávalos in 1956, because it was in situation of expiry. He fought in the Spanish Civil War for the Nationalist side, in the Terç de Requetès de la Mare de Déu de Montserrat and later the propaganda service under Dionisio Ridruejo's direction.
In 1977, he was appointed a senator in the Cortes Constituyentes by the Spanish king Juan Carlos I. He was also appointed chief of the Romance literature section of the Consejo Superior de Investigaciones Científicas (CSIC, "Superior Council of Scientific Investigations").
Riquer was a member of the Real Academia Española since 1965, president of the Real Academia de Buenas Letras de Barcelona, and corresponding member of numerous foreign institutions. He was the emeritus chair of Literaturas Románicas (Romance Literature) at the University of Barcelona, which he held from 1950 to 1984. He was viceroy of the university in 1965–6 and viceroy of the Autonomous University of Barcelona from 1970 to 1976. He is the founder and honorary president of the Sociedad Roncesvals, dedicated to the study of the chanson de geste and cantar de gesta.
