The Orchestra at the Opera (c. 1870) is an oil-on-canvas painting by the French artist Edgar Degas (1834–1917).

[1] The musicians depicted in the orchestra pit of the Salle Le Peletier the home of the Paris Opera (from 1821 until it burnt down in 1873) are mostly portraits of friends of Degas, foremost among them pictorially the bassoonist and composer Désiré Dihau (1838–1909), who commissioned the painting, at work on his instrument, and the cellist Louis-Marie Pilet (1815–1877) on his string instrument.

Above the musicians can be seen only the legs and tutus of the dancers onstage, their figures cropped by the edge of the painting.

Art historian Charles Stuckey has compared the viewpoint to that of a distracted spectator at a ballet, and says that "it is Degas' fascination with the depiction of movement, including the movement of a spectator's eyes as during a random glance, that is properly speaking 'Impressionist'.

He would depict dancers frequently for the rest of his career, and it is for his ballet pictures that he remains best known.
