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.

Phallus paintings in Bhutan are esoteric symbols, which have their origins in the Chimi Lhakhang monastery near Punakha, the former capital of Bhutan. The village monastery was built in honour of Lama Drukpa Kunley who lived at the turn of the 16th century and who was popularly known as the "Mad Saint" (nyönpa) or “Divine Madman” for his unorthodox ways of teaching, which amounted to being bizarre and shocking. These explicit paintings have become embarrassing to many of the country's urbanites, and this form of folk culture is informally discouraged in urban centers as modern Abrahamic cultural norms of shaming the human body and sexuality have spread in Bhutan's urban centers.
