François van Campenhout (5 February 1779 – 24 April 1848) was a Belgian opera singer, conductor and composer.
After he had been a violist at the Théâtre de la Monnaie (or Muntschouwburg) in Brussels for a while, he started a career as a tenor at the Opera in Ghent.
This was the beginning of a successful opera career, which brought him to Brussels, Antwerp, Paris, Amsterdam, The Hague, Lyon and Bordeaux.
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).
