G-Funk Classics, Vol. 1 & 2 is the debut studio album by American singer Nate Dogg. Vol. 1 of the album was originally released through Death Row Records on January 14, 1997, but was taken off the market a week after its release due to legal problems at Death Row Records. It was then rereleased as a two-volume set by Breakaway Entertainment on July 21, 1998. The first volume was recorded during his tenure at Death Row Records, while the second volume was recorded after. The album made it to number 58 on the Billboard 200 and number 20 on the Top R&B/Hip-Hop Albums. The album produced four singles, with two top 40 singles: "Never Leave Me Alone", which was released on October 22, 1996, through Death Row Records and peaked at number 33 on the Billboard Hot 100.

"Nobody Does It Better", which became his biggest hit as a solo artist, peaked at number 18 on the Hot 100; "These Days", released through Death Row Records; and "I Don't Wanna Hurt No More", released in 1998 through Breakaway. The song "These Days" was previously featured on the first disc of the soundtrack of the movie Gang Related, released in 1997 through Death Row Records, and the song was released as a 12-inch promo on the B-side on 2Pac's single "Lost Souls", also on the soundtrack. It also had a release in 1997 as a promo version through Death Row Records. The track listing of the original print included an error: "Crazy, Dangerous" was credited as featuring Big Syke. According to Butch Cassidy, the album sold around 33,000 copies in the first week.

The album was first advertised by Death Row Records four years prior to its release.
