David Geffen (born February 21, 1943) is an American record executive, film producer, theatrical producer and philanthropist. Geffen is noted for creating Asylum Records in 1970 (which merged with Elektra Records in 1972 to form Elektra/Asylum Records), and Geffen Records in 1980, along with his later role as one of the three founders of Dreamworks SKG in 1994.

He was born into a European-Jewish family in Brooklyn, New York. David Geffen's father, Abraham Geffen, is of Polish ancestry, and his mother Batya Volovskaya is of Ukrainian ancestry. Both were immigrants from Europe who met in the Land of Palestine (before the creation of Israel) and then moved to Brooklyn. Geffen graduated from New Utrecht High School in Brooklyn, then attended Santa Monica College (then known as Santa Monica City College) but soon dropped out. He then attended night school at Brooklyn College for three semesters before again dropping out. He also briefly attended the University of Texas at Austin before dropping out. His mother owned a clothing store, Chic Corsets By Geffen, in Borough Park, Brooklyn. David's older brother Mitchell Geffen was an attorney who attended UCLA Law School and later settled in Encino, California (Mitchell Geffen was the father of two daughters, who are David's closest surviving relatives).

Geffen began his entertainment career in the mailroom at the William Morris Agency, where he quickly became an agent. In order to obtain the WMA job, he had to show proof of graduating college. Geffen forged a letter and submitted it to WMA. His colleagues in the mailroom included Barry Diller and Elliot Roberts, who later became David Geffen's partner in a management company. He was a hard worker, and spent his vacation time working in the mailroom of the Beverly Hills office of the WMA. He left William Morris to become a personal manager and was immediately successful with Laura Nyro and Crosby, Stills and Nash. In the process of looking for a record deal for young Jackson Browne, Ahmet Ertegün suggested that Geffen start his own record label.
