Chögyam Trungpa (Wylie: Chos rgyam Drung pa; March 5, 1939 – April 4, 1987) was a Buddhist meditation master and holder of both the Kagyu and Nyingma lineages, the eleventh Trungpa tülku, a tertön, supreme abbot of the Surmang monasteries, scholar, teacher, poet, artist, and originator of a radical re-presentation of Shambhala vision.

Recognized both by Tibetan Buddhists and by other spiritual practitioners and scholars as a preeminent teacher of Tibetan Buddhism, he was a major figure in the dissemination of Buddhism to the West, founding Vajradhatu and Naropa University and establishing the Shambhala Training method.

Among his contributions are the translation of numerous Tibetan texts, the introduction of the Vajrayana teachings to the West, and a presentation of the Buddhadharma largely devoid of ethnic trappings. Trungpa coined the term crazy wisdom. Some of his teaching methods and actions were the topic of controversy during his lifetime and afterwards.
