Jean-Pierre Guézec (19 August 1934 – 9 March 1971) was a French composer.
Born in Dijon, Guézec studied music at the Conservatoire de Paris with Darius Milhaud, Jean Rivier and Olivier Messiaen.
His very personal language is influenced by the techniques of modern painting, in particular those of Mondrian and Vasarely.
His research led him to compose works in which the contrasts of sound materials and a very original sense of colour dominate, as evidenced by the title of his works.
Xenakis dedicated his 1971 composition Charisma to Guézec.
