Deepak Chopra (/ˈdiːpɑːk ˈtʃoʊprə/) (born October 22, 1947) is a controversial Indian-American author, New-Age guru, alternative-medicine advocate, public speaker and physician. Through his several dozen books and videos, he has become one of the best-known and wealthiest figures in the holistic-health movement.

Chopra obtained his medical degree in India before emigrating in 1970 to the United States, where he specialized in endocrinology and became Chief of Staff at the New England Memorial Hospital (NEMH). In the 1980s he began practicing transcendental meditation (TM) and in 1985 resigned his position at NEMH to establish the Maharishi Ayurveda Health Center. Chopra left the TM movement in 1994 and founded the Chopra Center for Wellbeing.
