The Firebird is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1910 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Michel Fokine, who collaborated with Alexandre Benois on a scenario based on the Russian fairy tales of the Firebird and the blessing and curse it possesses for its owner. It was first performed at the Opéra de Paris on 25 June 1910 and was an immediate success, catapulting Stravinsky to international fame. Although designed as a work for the stage, with specific passages accompanying characters and action, the music achieved equal if not greater recognition as a concert piece.

Stravinsky was a young and virtually unknown composer when Diaghilev commissioned him to compose The Firebird for the Ballets Russes. Its success was the start of Stravinsky's partnership with Diaghilev, which would subsequently produce further ballet productions until 1928, including Petrushka (1911), The Rite of Spring (1913), and Apollo (1928)

Shortly after the completion of The Firebird, Stravinsky wrote a piano solo reduction of the whole ballet.^[36] Besides the complete 50-minute ballet score of 1909–10, Stravinsky arranged three suites for concert performance which date from 1911, 1919, and 1945.

In 1945, shortly before he acquired American citizenship, Stravinsky was contacted by Leeds Music with a proposal to revise the orchestration of his first three ballets in order to recopyright them in the United States. The composer agreed, setting aside work on the finale of his Symphony in Three Movements. He proceeded to fashion a new suite based on the 1919 version, adding to it and reorchestrating several minutes of the pantomimes from the original score.
