Deepak Chopra (Hindi: दीपक चोपड़ा; born October 22, 1946) is a Indian medical doctor, public speaker, and writer on subjects such as spirituality, Ayurveda and mind-body medicine. Chopra began his career as an endocrinologist and later shifted his focus to alternative medicine. Chopra now runs his own medical center, with a focus on mind-body connections. He is also a lecturer at the Update in Internal Medicine event, sponsored by Harvard Medical School's Department of Continuing Education and the Department of Medicine.

Chopra was a top assistant to Maharishi Mahesh Yogi before launching his own career in the late 1980s by publishing self-help books on New Age spirituality and alternative medicine.

A friend of Michael Jackson for 20 years, Chopra came to widespread public attention in July 2009 when he criticized the "cult of drug-pushing doctors, with their co-dependent relationships with addicted celebrities," saying he hoped Jackson's death, attributed to an overdose of a prescription drug, would be a call to action.
