The Carnival of Oruro is a religious and cultural festival in Oruro, Bolivia. It has been celebrated since the 18th century. Originally an indigenous festival, the celebration later was transformed to incorporate a Christian ritual around the Virgin of Candelaria (Virgin of Socavón). The carnival is one of UNESCO's Masterpieces of the Oral and Intangible Heritage of Humanity.

Throughout the festival, more than 48 groups of folk dancers specializing in 18 different folk dances perform a pilgrimage to the Shrine of the Tunnel every Saturday of the carnival in a traditional parade. The traditional Llama llama or Diablada became the leading traditional dance of the festival.
