Jack Kornfield (born 1945) is one of the pre-eminent and most popular teachers in the vipassana movement of American Theravada Buddhism. He trained as a Buddhist monk in Thailand, Burma and India, including as a student of the venerated Thai monk Ajahn Chah. He has taught meditation worldwide since around 1974, and is particularly noted for the humor in his dharma talks.
After graduating from Dartmouth College in 1967, Kornfield joined the Peace Corps and was assigned to the Public Health Service in northeast Thailand, which is home to several of the world's oldest Buddhist forest monasteries. Here he met Ajahn Chah, who became his teacher for many years. Upon returning to the United States in 1972, Kornfield co-founded the Insight Meditation Society in Barre, Massachusetts, with fellow meditation teachers Sharon Salzberg and Joseph Goldstein.
Kornfield holds a Ph.D. in clinical psychology from Saybrook Institute. He is also a founding teacher of the Spirit Rock Center in Woodacre, California, where he currently lives and teaches.
Kornfield has become one of the key teachers to introduce Theravada Buddhist practice to the West. For many years his work has focused on integrating and bringing alive the great Eastern spiritual teachings in an accessible way for Western students and Western society. His books, audio tapes and teachings have acted as an inspiration for countless Western students of Buddhism.
His books include Seeking the Heart of Wisdom, A Still Forest Pool, Stories of the Spirit, Stories of the Heart, the national bestseller A Path with Heart and After the Ecstasy the Laundry as well as a number of meditation and dharma audiotapes.
Kornfield lectures were featured by Joe Frank on his radio series "The Other Side."
