Jamyang Khyentse Wangpo, also known by his tertön title, Pema Ösel Dongak Lingpa, was a teacher, scholar and tertön of 19th-century Tibet. He was a leading figure in the Rimé movement.

Tertön is a term within Tibetan Buddhism meaning a person who is a discoverer of ancient hidden texts or terma. Many tertöns are considered to be incarnations of the twenty five main disciples of Padmasambhava, who foresaw a dark time in Tibet. He and his consort Yeshe Tsogyal hid teachings to be found in the future to benefit beings. A vast system of transmission lineages developed. Scriptures from the Nyingma school were updated by terma discoveries, and terma teachings have guided many Tibetan Bon and Buddhist practitioners.
