Isidoro Ocampo (20 June 1910, Veracruz — 4 February 1983, Mexico City) was a Mexican artist during the Mexican Muralism era, best known for his graphic work. Much of his career was dedicated to teaching, which kept his artistic output low, but he was also a founding member of the Taller de Gráfica Popular and the Sociedad Mexicana de Grabadores as well as member of the Liga de Escritores y Artistas Revolucionarios and the Salón de la Plástica Mexicana.
