François Glorieux (27 August 1932 – 22 September 2023) was a Belgian pianist, conductor, composer, musicologist, and academic teacher who performed internationally.

As a pianist, he received the Harriet Cohen International Music Award in 1967, toured in Germany and Austria with conductor André Cluytens, and later focused on improvisation.

He began studies at the Royal Conservatory of Ghent at age 17, piano with Marcel Gazelle and composition with George Lonque.

[2][3] As a composer, Glorieux was inspired by Debussy and Ravel, jazz, blues and Latin-American rhythms.

He improvised in free forms, with sometimes sudden shifts in dynamics, tempo and rhythm, with "wit, refinement and cosmopolitan sophistication".
