Emilio Herrera Linares (February 13, 1879, Granada, Spain – September 13, 1967, Geneve, Switzerland) ) was a Spanish military engineer and physicist. He graduated from the military academy of Guadalajara in 1902; he subsequently researched aeronautics, including a brief period at the University of Santander. He was father of the poet José Herrera Petere. He is best known for his work in cosmology and pioneering studies for high-altitude flight, spaceflight, computing, and for designing a pressurized space suit that was to be used in a planned stratospheric balloon flight in 1936.
During the Spanish Civil War (1936-1939), he remained loyal to the Second Spanish Republic. In 1937, he was made a general. He was a minister in several governments of the republic in exile, and president of the republic between 1960 and 1962.
