The Sleeping Beauty is a ballet in a prologue and three acts to music by Pyotr Ilyich Tchaikovsky, his Opus 66, completed in 1889. It is the second of his three ballets and, at 160 minutes, his second-longest work in any genre. The original scenario was by Ivan Vsevolozhsky after Perrault's La belle au bois dormant, or The Beauty Sleeping in the Forest; the first choreographer was Marius Petipa. The premiere took place at the Mariinsky Theatre in St. Petersburg on January 15, 1890, and from that year forward The Sleeping Beauty has remained one of the most famous of all ballets.

Ballet is a type of performance dance that originated during the Italian Renaissance in the fifteenth century and later developed into a concert dance form in France and Russia. It has since become a widespread and highly technical form of dance with its own vocabulary. Ballet has been influential globally and has defined the foundational techniques which are used in many other dance genres and cultures. Various schools around the world have incorporated their own cultures. As a result, ballet has evolved in distinct ways.
