Apollo (Attic, Ionic, and Homeric Greek: , Apollon ( ); Doric: , Apellon; Arcadocypriot: , Apeilon; Aeolic: , Aploun; ) is one of the most important and complex of the Olympian deities in classical Greek and Roman religion and Greek and Roman mythology. The ideal of the kouros (a beardless, athletic youth), Apollo has been variously recognized as a god of music, truth and prophecy, healing, the sun and light, plague, poetry, and more. Apollo is the son of Zeus and Leto, and has a twin sister, the chaste huntress Artemis. Apollo is known in Greek-influenced Etruscan mythology as Apulu.

Apollo (originally Apollon musagète and variously known as Apollo musagetes, Apolo Musageta, and Apollo, Leader of the Muses) is a ballet in two tableaux composed between 1927 and 1928 by Igor Stravinsky. It was choreographed in 1928 by twenty-four-year-old George Balanchine, with the composer contributing the libretto. The scenery and costumes were designed by André Bauchant, with new costumes by Coco Chanel in 1929. The scenery was executed by Alexander Shervashidze, with costumes under the direction of Mme. A. Youkine. The American patron of the arts Elizabeth Sprague Coolidge had commissioned the ballet in 1927 for a festival of contemporary music to be held the following year at the Library of Congress in Washington, D.C.
