Drukpa Kunley (1455–1529), also known as Kunga Legpai Zangpo, Drukpa Kunleg, and Kunga Legpa, the Madman of the Dragon Lineage, was a Tibetan Buddhist monk, missionary, and poet in the Drukpa Kagyu lineage of the Mahamudra tradition. He was trained at Ralung Monastery under siddha Pema Lingpa. However, by the age of 25, he had returned his monastic vows to take a wife, whose name was Tsewang Dzom. He is often counted among the Nyönpa.
