François van Campenhout (5 February 1779 ? 24 April 1848) was a Belgian opera singer, conductor and composer. He composed the music for the Belgian national anthem, the Brabançonne.
Campenhout wrote a large number of works: operas such as Grotius ou le Château de Lovesteyn and Passe-Partout, which were successful, and he also composed ballet music, symphonies and choir music. He wrote the music of the Brabançonne in September 1830, to a text by Alexandre Dechet (Jenneval).
