Federico Amodeo (8 October 1859, Avellino – 3 November 1946, Naples) was an Italian mathematician, specializing in projective geometry, and a historian of mathematics. He received in 1883 his Ph.D. (laurea) in mathematics from the University of Naples, where he became an instructor (libero docente) and from 1885 to 1923 taught projective geometry. He also taught as a professor in Naples at the Istituto Tecnico "Gianbattista Della Porta" from 1890 to 1923, when he retired. In 1890–1891 he visited the geometers at the University of Turin.
