Samson was an opera by the French composer Jean-Philippe Rameau with a libretto by Voltaire.
 The work was never staged due to censorship, although Voltaire later printed his text.
 Rameau intended the opera on the theme of Samson and Delilah as the successor to his debut "Hippolyte et Aricie", which premiered in October 1733.
 Like "Hippolyte", "Samson" was a "tragédie en musique" in five acts and a prologue.
 Voltaire had become a great admirer of Rameau's music after seeing "Hippolyte" and suggested a collaboration with the composer in November 1733.
 The opera was complete by late summer 1734 and went into rehearsal.
 However, a work on a religious subject with a libretto by such a notorious critic of the Church was bound to run into controversy and "Samson" was banned.
 An attempt to revive the project in a new version in 1736 also failed.
 The score is lost, although Rameau recycled some of the music from "Samson" in his later operas.
