Yin Shun (印順導師, Yinshun Daoshi) (12 March 1906–4 June 2005) was a well-known Buddhist monk and scholar in the tradition of Chinese Mahayana Buddhism. Yin Shun's research helped bring forth the ideal of Humanistic Buddhism, a leading mainstream Buddhist philosophy studied and upheld by many practioners. His work also regenerated interest in the long-ignored Agamas (Nikayas) among the Chinese Buddhist society, and his ideas are echoed by Theravadin teacher Bhikkhu Bodhi. As a contemporary master, he was most popularly known as the mentor of Venerable Master Cheng Yen (Pinyin: Zhengyan), the founder of the Tzu-Chi Buddhist Foundation, as well as the teacher to several other monastics. He was known affectionately by many Buddhists as their mentor.
