Junior M.A.F.I.A. is an American East-Coast hip-hop group formed and mentored by The Notorious B.I.G. who featured on and executive produced their debut album, Conspiracy in 1995. The backronym M.A.F.I.A. stands for Masters At Finding Intelligent Attitudes.

The group’s members were Lil' Kim, Kleptomaniac, The Snakes (consisting of blood cousins Trife & Larceny who now go by Blake C. and Banger respectively), and The 6’s (including Lil' Cease, Bugsy, Capone, Cheek Del Vec, and Nino Brown).

The success of the group’s singles “Player’s Anthem”, “I Need You Tonight”, and “Get Money” helped launch the career of Lil' Kim and Lil' Cease as solo artists.

The group’s foundation became shaky following the murder of The Notorious B.I.G. in 1997. A feud and eventual lawsuit that brewed between Lil' Cease and Lil' Kim made things worse. In 2005, Cease, Banger, and Kleptomaniac released the album Riot Musik and two DVDs under the Junior M.A.F.I.A. name, but its performance was lukewarm compared to that of Conspiracy.

In 2019, Lil' Kim and Lil' Cease buried the hatched and re-united at a dinner party alongside the other remaining members of Junior M.A.F.I.A. When asked about a re-union album, Kim said: “Just wait and see. I’ve got some special things planned, don’t worry. I can’t tell you nothing right now”.
