Gonzalo de Olavide y Casenave (28 March 1934 – 4 November 2005) was a Spanish composer born in Madrid.

Olavide studied composition initially with Victorino Echevarría at the Conservatorio Superior de Madrid, then in Belgium at the conservatories of Antwerp and Brussels. He attended the Darmstadt Internationale Ferienkurse für Neue Musik where he worked with Pierre Boulez and Luciano Berio, and later studied with Karlheinz Stockhausen and Henri Pousseur at the Second, Third, and Fourth Cologne Courses for New Music in 1964–65, 1965–66, and 1966–67. For twenty years he lived and worked in Geneva, returning to Spain in 1991.

Olavide composed orchestral, chamber, solo, and electronic music. In 1986 he received the Premio Nacional de Música, and in 2001 the Premio Reina Sofia.
