Alphonse Zoé Charles Renaud de Vilbac (* 3. Juni 1829 in Montpellier; † 19. März 1884 in Ixelles) was a French organist and composer.
At the age of thirteen he came to the Conservatoire de Paris, where he studied organ with François Benoist and composition with Jacques Fromental Halévy. Shortly after his fifteenth birthday, in 1844, he won the second Premier Grand Prix de Rome with the cantata Le Renégat de Tanger
In 1855 he became organist at the Merklin-Schültze organ of the Saint-Eugène-Sainte-Cécile church in Paris. He held the position until 1871; his successor was Raoul Pugno. Rebaud de Vilbac composed an opera and an operetta, as well as a number of orchestral and piano compositions. He also wrote piano transcriptions (e.g. Saint-Saëns' Danse macabre). He also wrote a pedagogical work, Méthode de l'Orgue ou d'Harmonium.
