Kyabjé Drubwang Padma Norbu Rinpoche (Tibetan: པདྨ་ནོར་བུ་, Wylie: pad ma nor bu), 1932 – 27 March 2009, was the 11th throneholder of the Palyul Lineage of the Nyingma school of Tibetan Buddhism, and said to be an incarnation of Vimalamitra. He was widely renowned in the Tibetan Buddhist world as a master of Dzogchen. He was one of a very few teachers left from his generation who received all his training (in the traditional sense) in Tibet under the guidance of what Tibetan Buddhists consider to be fully enlightened teachers.
