Ivo Malec (30 March 1925 in Zagreb – 14 August 2019 in Paris) was a Croatian-born French composer, music educator and conductor. One of the earliest Yugoslav composers to obtain high international regard, his works have been performed by symphony orchestras throughout Europe and North America.

Coming from a rather 'classical' background, he met Pierre Schaeffer whom he considers his 'true and only master'; Schaeffer's teachings turned Malec into one of the most important leaders of the Groupe de recherches musicales. Since then he dedicated himself to a more radical style. He received a number of awards including the Grand Prix National de Musique in 1992. He was resident in France since 1955 and taught at the Paris Conservatoire from 1972 to 1990 where he taught composers such as Édith Canat de Chizy, Denis Dufour, Philippe Hurel, Philippe Leroux and Gerard Pesson.

Malec's approach to composition which in ways is similar to that of Denis Dufour or Xenakis is the emphasis on all aspects of sound including texture, density, movement, timbre and notably sonic character and form and the use of sound objects.
