Dungsey Thinley Norbu Rinpoche (1931-2011) was a major modern teacher in the Nyingma lineage of Tibetan Buddhism. He was the eldest son of Kyabje Dudjom Rinpoche, the former head of the Nyingma lineages.

Rinpoche was the father of Dzongsar Jamyang Khyentse Rinpoche and of Garab Rinpoche. His association with the Dudjom Lineage is a long one: he is held to be the incarnation of Tulku Drime Oser, one of seven sons of Dudjom Lingpa (1835-1904). He was also was considered to be an emanation of Longchen Rabjam, the great 14th century Nyingma scholar and siddha who composed the Seven Treasuries.

In his youth in Tibet, Rinpoche studied for nine years at Mindrolling Monastery, one of the six major Tibetan monasteries of the Nyingma school. Having fled his homeland, he spent some time in Bhutan, where his sons were born. He was the chief architect of the Thimphu Memorial Chorten, which he built in 1974, under the guidance of his father, to honour the memory of the third King of Bhutan, Jigme Dorji Wangchuck (1928-72).

Dungse Rinpoche lived in Bhutan since mid-’50s and has many devotees all over Bhutan. He left Bhutan in the mid-’70s in deferment to the directives of his father, the late Kyabje Dudjom Jigdrel Dorje Rinpoche, to teach in the West. In later years he divided his time primarily between the United States and Nepal.

Rinpoche's best known works in English are Magic Dance: The Display of the Self-nature of the Five Wisdom Dakinis. (1982), White Sail: Crossing the Waves of Ocean Mind to the Serene Continent of the Triple Gems (1992) and A Cascading Waterfall of Nectar (2006).
