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.

A phallus is a penis, an object that resembles a penis, or a mimetic image of an erect penis. In art history, a figure with an erect penis is described as ithyphallic.
