La Bayadère (en. The Temple Dancer) is a ballet, originally staged in four acts and seven tableaux by French choreographer Marius Petipa to the music of Ludwig Minkus. The ballet was staged especially for the benefit performance of the Russian Prima ballerina Ekaterina Vazem, who created the principal role of Nikiya.

La Bayadère was first presented by the Imperial Ballet at the Imperial Bolshoi Kamenny Theatre in St. Petersburg, Russia, on 4 February [O.S. 23 January] 1877. From the first performance the ballet was universally hailed by contemporary critics as one of the choreographer Petipa's supreme masterpieces, particularly the scene from the ballet known as The Kingdom of the Shades, which became one of the most celebrated pieces in all of classical ballet. By the turn-of-the 20th century, The Kingdom of the Shades scene was regularly extracted from the full-length work as an independent showpiece, and it has remained so to the present day.

Nearly all modern versions of La Bayadère are derived from the Kirov Ballet's production of 1941, which was a severely redacted edition staged by Vakhtang Chabukiani and Vladimir Ponomarev in Leningrad in 1941. Natalia Makarova's 1980 production of La Bayadère for American Ballet Theatre was the first full-length production to find a permanent place in the repertories of western ballet troupes, having been staged by several theatres throughout the world. Makarova's version is itself derived from Chabukiani and Ponomarev's 1941 redaction for the Mariinsky Theatre.

La Bayadère was the creation of the dramatist Sergei Khudekov and of Marius Petipa, the renowned Premier maître de ballet of the St. Petersburg Imperial Theatres. The music was composed by Ludwig Minkus, who from 1871 until 1886 held the official post of Ballet Composer to the St. Petersburg Imperial Theatres.

Khudekov's libretto for La Bayadère (meaning The Temple Dancer or The Temple Maiden) tells the story of the bayadère Nikiya and the warrior Solor, who have sworn eternal fidelity to one another. The High Brahmin, however, is also in love with Nikiya and learns of her relationship with Solor. Moreover, the Rajah Dugmanta of Golconda has selected Solor to wed his daughter Gamzatti (or Hamsatti, as she is known in the original production), and Nikiya, unaware of this arrangement, agrees to dance at the couple's betrothal celebrations.

In his effort to have Solor killed and have Nikiya for himself, the jealous High Brahmin informs the Rajah that the warrior has already vowed eternal love to Nikiya over a sacred fire. But the High Brahmin's plan backfires when, rather than becoming angry with Solor, the Rajah decides that it is Nikiya who must die. Gamzatti, who has eavesdropped on this exchange, summons Nikiya to the palace in an attempt to bribe the bayadère into giving up her beloved. As their rivalry intensifies, Nikiya picks up a dagger in a fit of rage and attempts to kill Gamzatti, only to be stopped in the nick of time by Gamzatti's aya. Nikiya flees in horror at what she has almost done. As did her father, Gamzatti vows that the bayadère must die.

At the betrothal celebrations Nikiya performs a somber dance while playing her veena. She is then given a basket of flowers which she believes are from Solor, and begins a frenzied and joyous dance. Little does she know that the basket is from Gamzatti, who has concealed beneath the flowers a venomous snake. The bayadère then holds the basket too close and the serpent bites her on the neck. The High Brahmin offers Nikiya an antidote to the poison, but she chooses death rather than life without her beloved Solor.

In the next scene the depressed Solor smokes opium. In his dream-like euphoria he has a vision of Nikiya's shade (or spirit) in a nirvana among the star-lit mountain peaks of the Himalayas called The Kingdom of the Shades. Here, the lovers reconcile among the shades of other bayadères (in the original production of 1877 this scene took place in an illuminated enchanted palace in the sky). When Solor awakes, preparations are underway for his wedding to Gamzatti.

In the temple where the wedding is to take place the shade of Nikiya haunts Solor as he dances with Gamzatti. When the High Brahmin joins the couple's hands in marriage, the gods take revenge for Nikiya's murder by destroying the temple and all of its occupants. In an apotheosis, the shades of both Nikiya and Solor are reunited in death and eternal love.

La Bayadère was created especially for the benefit performance of Ekaterina Vazem, Prima ballerina of the St. Petersburg Imperial Theatres. The role of Solor was created by the forty-three-year-old Lev Ivanov, Premier danseur of the St. Petersburg Imperial Theatres, with the classical dances of the character Solor being performed by the younger Pavel Gerdt. The celebrated ballerina Maria Gorshenkova created the role of Gamzatti (or Hamsatti, as the character was known in the original production), while the role of the High Brahmin was created by Nikolai Golts. Dugmanta, the Rajah of Golconda was created by Christian Johansson, former Premier danseur of the St. Petersburg Imperial Theatres and an influential teacher. The lavish décor was designed by Mikhail Bocharov for Act I-scene 1; Matvei Shishkov for Act I-scene 2 and Act II; Ivan Andreyev for Act III-scene 1 and Act IV-scene 1; Heinrich Wagner for Act III-scene 2 The Kingdom of the Shades; and Piotr Lambin for the Act IV-scene 2 Apotheosis.

Petipa spent almost six months staging La Bayadère. During rehearsals, Petipa clashed with the Prima ballerina Vazem over the matter of her entrance in the ballet's final Grand pas d'action, while also experiencing many problems with the set designers who constructed the ballet's elaborate stage effects. Petipa was also worried that his new work would play to an empty house, as the Imperial Theatre's Director Baron Karl Kister increased the ticket prices to be higher than that of the Italian Opera, which at that time were expensive. The most celebrated and enduring passage of La Bayadère was Petipa's grand vision scene known as The Kingdom of the Shades. Petipa staged this scene as a Grand pas classique, completely devoid of any dramatic action. His simple and academic choreography was to become one of his most celebrated compositions, with the Sortie des bayadères of the thirty-two member Corps de ballet of shades arguably becoming his most celebrated composition of all.

Petipa's final revival of La Bayadère was first given on December 15 [O.S. December 3] 1900 especially for the dual benefit performance of the Imperial Theatre's Premier danseur Pavel Gerdt and the Prima ballerina Mathilde Kschessinskaya. Among Petipa's changes for this revival was the re-setting of the scene The Kingdom of the Shades from an enchanted castle in the sky on a fully lighted stage, to a dark and rocky setting on the peaks of the Himalayas. Petipa swelled the number of dancers in the Corps de ballet from thirty-two to forty-eight, making the illusion of descending spirits all the more effective in the famous Sortie des bayadères.

In March 1903, the scene The Kingdom of the Shades was performed independently during a gala performance at Peterhof Palace in honor of a state visit from Kaiser Wilhelm II. This is the earliest known occasion where the scene The Kingdom of the Shades was performed as an independent concert piece.
