Cheng Yen or Shih Cheng Yen(; born Chin-Yun Wong; 14 May 1937) is a Taiwanese Buddhist nun (bhikkhuni), teacher, and philanthropist. She is the founder of the Buddhist Compassion Relief Tzu Chi Foundation, ordinarily referred to as Tzu Chi, a Buddhist humanitarian organization based in Taiwan. In the West, she is sometimes referred to as the "Mother Teresa of Asia". Cheng Yen was born in Taiwan during the Japanese occupation. She developed an interest in Buddhism as a young adult, ordaining as a Buddhist nun in 1963 under the well known proponent of humanistic Buddhism, master Yin Shun. After an encounter with a poor woman who had a miscarriage, and a conversation with Roman Catholic nuns who talked about the various charity work of the Catholic Church, Cheng Yen founded the Tzu Chi Foundation in 1966 as a Buddhist humanitarian organization.

Cheng-Yen grew up during the Japanese occupation of Taiwan during World War II, where she witnessed the devastating effects of war and experienced the bombings in Taiwan. These experiences were credited as contributing to what she regarded as the truth behind the concept of impermanence. In 1945, when she was eight years old, she looked after her sick brother in a hospital for eight months, and so learned more closely about people's pain and helplessness.
