Nuo opera or Nuo drama is one of China's most popular folk operas. Characterized by its special features such as ferocious masks, unique dresses and adornments, the strange language used in performance, and mysterious scenes, Nuo opera has been selected as one of the non-material cultural legacies of China. The opera is a religious performance intrinsic to the culture of Nuoism, a type of Chinese folk religion. The purpose of Nuo opera is to drive away devils, disease and evil influences, and also to petition for blessings from the gods. Singing and dancing are included in Nuo opera and performers wear costumes and masks.

Nuo folk religion, or extendedly, Chinese popular exorcistic religion, is a variant of Chinese folk religion with its own system of temples, rituals, orders of priests, and gods that is interethnic and practiced across central and southern China but is also intimately connected to the Tujia people. It arose as an exorcistic religious movement, which is the original meaning of nuó. It has strong influences from Taoism.
