Hahoe byeolsingut talnori (하회별신굿탈놀이, 河回別神굿탈놀이) or "Hahoe special ritual drama to the gods" is a Korean masked dance-drama performed every three, five, or ten years at the request of the village deity in Hahoe, Andong, North Gyeongsang Province. The village is a UNESCO World Heritage Site, the dance-drama an Important Intangible Cultural Property, and a collection of thirteen (13) masks are a National Treasure. The ritual shares some of the major themes of Korean masked drama and Korean shamanism, namely satire and the ridicule of apostate Buddhist priests and the nobility.
