G-Unit, an abbreviation for Guerilla Unit, is a rap group founded by 50 Cent. The group first garnered a following in the underground New York scene by independently releasing several mixtapes. The group's founder, Queens-based rapper 50 Cent, officially brought the group mainstream success by establishing it as a division at Interscope Records. Since signing to the label, G-Unit's members have released solo albums.

G-Unit was founded shortly after 50 Cent left Columbia Records. The rapper was interested in working with fellow Queens-based rappers, including Lloyd Banks and Tony Yayo These rappers collectively established the group as a whole; however, after Yayo got a prison sentence 50 Cent signed Young Buck and along with himself and Banks became the three faces of G-Unit. 50 Cent later went on to sign The Game, Mobb Deep, M.O.P, Olivia, Spider Loc and Mase. The Game and 50 Cent had "beef" after the realease of The Games debut, and 50 dropped him from G-Unit records.

50 Cent gained solo success after jointly signing to Dr. Dre's Aftermath Entertainment and Eminem's Shady Records, collectively, divisions of Interscope Records. After the release of his album Get Rich or Die Tryin', 50 Cent and Sha Money XL founded G-Unit Records.

The G-Unit clique later released their debut album Beg For Mercy, on November 14, 2003. The album peaked at #2 on the Billboard charts and sold over 4 million units.

Method Man recently confirmed recording with Young Buck and Kokane on a remake of Bob Marley's song "Roll It Up." This track marks the first official collaboration between New York supergroups Wu Tang and G Unit.
