2001 (sometimes referred to as The Chronic 2001, Chronic 2001 or The Chronic 2) is the second studio album by American rapper and producer Dr. Dre. It was released on November 16, 1999, by Interscope Records as the follow-up to his 1992 debut album The Chronic. The record was produced primarily by Dr. Dre and Mel-Man, as well as Lord Finesse, and features several guest contributions from fellow American rappers such as The D.O.C., Hittman, Snoop Dogg, Kurupt, Xzibit, Nate Dogg, and Eminem. 2001 exhibits an expansion on his debut's G-funk sound and contains gangsta rap themes such as violence, promiscuity, drug use, street gangs, sex and crime.

The album debuted at number 2 on the U.S. Billboard 200 chart, selling 516,000 copies in its first week. It produced 3 singles that attained chart success and has been certified 6× Platinum by the RIAA; as of August 2015 the album has sold 7,800,000 copies in the United States. 2001 received generally positive reviews from critics, many of whom praised the music although some found the lyrics objectionable.

The title "Chronic 2000" was the original title for former Death Row Records artist Dr. Dre's anticipated second album, but Suge Knight took the title and used it for his album which forced Dre to retitle his album to 2001.
