Jesús Evaristo Díaz-Casariego y Fernández-Noriega (1912–1990) was a Spanish writer and publisher, popular especially during the early and mid-Francoism. Among some 60 books and booklets he wrote most are popular and semi-scientific historiographic works, though he was known chiefly as a novelist, especially as the author of Con la vida hicieron fuego (1953). In the early 1940s he managed a vehemently militant Francoist daily El Alcazár, yet in his youth and older age he was active as a Carlist. Today he is considered the author of second-rate literature, occasionally recognized as expert on Asturian culture and history.
