Benjamín Jarnés Y Millán (October 7, 1888–August 11, 1949) was a Spanish writer. Having been a soldier for a decade, he quit the army in 1920 and published his first novel in 1924. His second novel ''El profesor inútil'' (The Useless Professor, 1926) met with success and was followed by books such as ''El convidado de papel'' (1928) and ''Teoría del zumbel'' (1930). He was one of the contributors of the Madrid-based ''Revista de Occidente'' and the Valencia-based ''Orto'' magazine between 1932 and 1934.
