Daniel-François-Esprit Auber (French: [danjɛl fʁɑ̃swa ɛspʁi obɛːʁ]; 29 January 1782 – 12 May 1871) was a French composer and director of the Paris Conservatoire.

Born into an artistic family, Auber was at first an amateur composer before he took up writing operas professionally when the family's fortunes failed in 1820. He soon established a professional partnership with the librettist Eugène Scribe that lasted for 41 years and produced 39 operas, most of them commercial and critical successes. He is mostly associated with opéra-comique and composed 35 works in that genre. With Scribe he wrote the first French grand opera, La Muette de Portici (The Dumb Woman of Portici) in 1828, which paved the way for the large-scale works of Giacomo Meyerbeer.

Auber held two important official musical posts. From 1842 to 1871 he was director of France's premier music academy, the Paris Conservatoire, which he expanded and modernised. From 1852 until the fall of the Second Empire in 1870 he was director of the imperial chapel in the Louvre, for which he wrote a substantial number of liturgical works and other religious music.

A devotee of Paris, Auber refused to leave the city when the Franco Prussian War led to the siege of Paris and the subsequent rise of the Paris Commune. He died in his house in Paris, aged 89, shortly before the French government regained control of the capital.
