Young was born in Compton, California, the first child of Theodore and Verna Young. His middle name, Romelle, is derived from his father's amateur R&B singing group, The Romells. His parents married in 1964, separated in 1968, and divorced in 1972. His mother later remarried and had three children: sons Jerome and Tyree (both deceased) and daughter Shameka.

Inspired by the Grandmaster Flash song "The Adventures of Grandmaster Flash on the Wheels of Steel", he often attended a club called Eve After Dark to watch many DJs and rappers performing live. He subsequently became a DJ in the club, initially under the name "Dr. J", based on the nickname of Julius Erving, his favorite basketball player. At the club, he met aspiring rapper Antoine Carraby, later to become member DJ Yella of N.W.A. Soon afterwards he adopted the moniker Dr. Dre, a mix of previous alias Dr. J and his first name, referring to himself as the "Master of Mixology". Eve After Dark had a back room with a small four-track studio. In this studio, Dre and Yella recorded several demos. In their first recording session, they recorded a song entitled "Surgery", with the lyrics "calling Dr. Dre to surgery" serving as the chorus to the song. He later joined the musical group World Class Wreckin' Cru under the independent Kru-Cut Records in 1984. The group would become stars of the electro-hop scene that dominated early 1980s West Coast hip hop. "Surgery", which was officially released after being recorded prior to the group's official formation, would prominently feature Dr. Dre on the turntable. The record would become the group's first hit, selling 50,000 copies within the Compton area.  Dr. Dre and DJ Yella also performed mixes for local radio station KDAY, boosting ratings for its afternoon rush-hour show The Traffic Jam. Dr. Dre's earliest recordings were released in 1994 on a compilation titled Concrete Roots. Stephen Thomas Erlewine of the website AllMusic described the compiled music, released "several years before Dre developed a distinctive style", as "surprisingly generic and unengaging" and "for dedicated fans only".  His frequent absences from school jeopardized his position as a diver on his school's swim team. After high school, he attended Chester Adult School in Compton following his mother's demands for him to get a job or continue his education. After brief attendance at a radio broadcasting school, he relocated to the residence of his father and residence of his grandparents before returning to his mother's house. He later dropped out of Chester to focus on performing at the Eve's After Dark nightclub.
