Paul Constant Eugène de Maleingreau (23 November 1887 - 9 January 1956) was a Belgian composer and organist.
From 1905 to 1912 he studied at the Brussels Conservatory where his principal teachers were Alfons Desmet, Paul Gilson and Edgar Tinel.
His pupils included Pierre Froidebise, Charles Koenig, Robert Kohnen, Marcel Druart, Paul Sprimont and Herman Roelstraete.
Gregorian plainsong forms the basis of most of Malengreau’s compositions, and indeed part of his output is intended for the liturgy.
While the chromaticism and cyclic treatment of themes reveal the influence of Franck, certain harmonic progressions are typical of Impressionist music.
