Trunyan (Balinese: ᬢ᭄ᬭᬸᬜᬦ᭄) or Terunyan is a Balinese village (banjar) located on the eastern shore of Lake Batur, a caldera lake in Bangli Regency, central Bali, Indonesia. The village is one of the most notable homes of the Bali Aga people, the others being the villages of Tenganan and Sambiran.
Some lithic tools found at Trunyan indicate a culture of hunters-gatherers.
Trunyan society consists of two main "castes", the banjar jero and the banjar jaba. The castes are based on bloodlines dating back to the Gelgel dynasty.
The Trunyanese worship a local god and patron of the village known as Ratu Gede Pancering Jagat, known by the Trunyanese as Bhatara Da Tonta. The local god is connected with the Batur volcano. Bhatara Da Tonta is rendered as a four-meter-tall Neolithic effigy.
