Victor Charles Paul Dourlen (3 November 1780 – 8 January 1864) was a French composer and music teacher at the Conservatoire de Paris during the first half of the nineteenth century. He is primarily known as a theorist on account of his treatises on harmony, based on the methods of Charles Simon Catel, which were widely used as reference works, especially his Traité d'harmonie (c. 1838), the Traité d'accompagnement pratique (c. 1840), and his Méthode élémentaire pour le pianoforte (c. 1820).
