Thrangu Rinpoche (Tibetan: ཁྲ་འགུ་, Wylie: Khra-'gu [ˈtʰran.ɡu ˈrinpotʃe]^{[need tone]}) was born in 1933 in Kham, Tibet. He is a prominent tulku (reincarnate lama) in the Kagyu school of Tibetan Buddhism, the ninth reincarnation in his particular line. His full name and title is the Very Venerable Ninth Khenchen Thrangu Tulku, Karma Lodrö Lungrik Maway Senge. "Khenchen" denotes great scholarly accomplishment, and the term "Rinpoche" is an honorific title commonly afforded to Tibetan lamas.

Thrangu Rinpoche was installed at Thrangu Monastery in Kham (eastern Tibet) after his identification by His Holiness the Sixteenth Karmapa and Tai Situ Rinpoche at age five. He is one of the principal lamas there, although Traleg Rinpoche is the supreme abbot of the complex. He fled to India following the Chinese communist invasion in 1959

At the age of thirty-five Thrangu Rinpoche took the geshe examination in Bengal and was awarded the degree of Geshe Lharampa, the highest degree conferred in the Gelug transmission (it is not uncommon for monks of other lineage to pursue studies in that tradition). He was subsequently awarded the Khenchen degree of the Kagyu tradition. He played a critical role in the recovery of important Buddhist texts that had been largely destroyed by the Chinese Communists. He was named Abbot of Rumtek monastery, the home monastery in exile of the Karmapa, and also of the Nalanda Institute for Higher Buddhist Studies at Rumtek.
