David Drew Pinsky, M.D. (born September 4, 1958), is an American board-certified internist and addiction medicine specialist. He is much more widely known in the U.S. as radio and TV personality "Dr. Drew", the co-host of the nationally syndicated radio talk show, Loveline, which he has hosted since 1984. On television he produces and hosts the VH1 show Celebrity Rehab with Dr. Drew and the MTV show Sex...With Mom and Dad. In 2009 a spinoff of Celebrity Rehab with Dr. Drew premiered named Sober House.

As a medical doctor, Pinsky is Assistant Clinical Professor of Psychiatry at the Keck School of Medicine at the University of Southern California, Medical Director for the Department of Chemical Dependency Services at Las Encinas Hospital in Pasadena, California, staff member at Huntington Memorial Hospital, and a private practitioner.

As The New York Times described it in February 2008, Pinsky's dual career in medicine and the mass media has required him to "navigat a precarious balance of professionalism and salaciousness."
