Drew Pinsky (born September 4, 1958 as David Drew Pinsky) is a board-certified physician and addiction medicine specialist, best known as co-host of the nationally syndicated radio talk show Loveline. On Loveline "Dr. Drew", as he is exclusively called, dispenses sound advice on a wide array of important issues related mostly to teenagers and young adults. Dr. Drew's partner Adam Carolla provides the humor with his comical analogies, often poking fun at the straight-laced Drew.

Dr. Drew was born in Pasadena, California, and his father was also a doctor. He majored in biology at Amherst College, graduating in 1980, and earned his M.D. at the University of Southern California School of Medicine in 1984. He started doing Loveline as a local show on radio station KROQ while still a student, with no pay at first. He served his residency at Huntington Memorial Hospital in Pasadena, and eventually became chief resident there before moving into private practice. Dr. Drew married in 1991, and had triplets with his wife Susan in 1992. Loveline went national in 1995, and the television version began the following year. The show ran on MTV for four years, and still continues on radio.

In addition to his radio show and medical career, Pinsky also has become quite popular on television talk shows, where his medical expertise and relationship counseling abilities are highly valued. He served as "health and human relations expert" on the first season of the U.S. TV series Big Brother in 2000. In 2003, he released a book called Cracked, recounting his experiences running the drug-addiction rehab clinic at Las Encinas Hospital in Pasadena. He also contributed to the book When Painkillers Become Dangerous: What Everyone Needs to Know About OxyContin and Other Prescription Drugs, published in 2004.

Dr. Drew often serves as a guest-speaker at college and university campuses throughout the United States.

He made his acting debut in 2004, playing the father of Mary-Kate and Ashley Olsen in New York Minute.
