Roberto Lupi (28 November 1908 – 17 April 1971) was an Italian composer, conductor, and music theorist.
Born in Milan and trained at the conservatory there, he began his conducting career in 1937.
His compositions of experimental music included large-scale works for chorus and orchestra, chamber music, and stage works.
However, Lupi's most widely heard piece was his Armonie del pianeta Saturno for oboe (or, sometimes, trumpet), harp and strings which was played each night from 1954 to 1986 at the close of RAI television transmissions.
He held the chair in composition at the Florence Conservatory from 1941 until his death and published three books on music theory, the last of them posthumously.
From the 1950s his theoretical approach and his compositions, especially his stage works, were strongly influenced by the ideas of Rudolf Steiner.
