L'étoile is an opéra bouffe in three acts by Emmanuel Chabrier with a libretto by Eugène Leterrier and Albert Vanloo.

Alexis-Emmanuel Chabrier was a French Romantic composer and pianist. His bourgeois family did not approve of a musical career for him, and he studied law in Paris and then worked as a civil servant until the age of thirty-nine while immersing himself in the modernist artistic life of the French capital and composing in his spare time. From 1880 until his final illness he was a full-time composer.
