Mafia K-1 Fry sometimes stylized as Mafia K'1 Fry is a French collective of hip hop artists, rappers, beatboxers, DJs, MCs and music producers mostly coming from the Val-de-Marne and the Orly-Choisy-Vitry-Joinville axis (being locations in Orly - Choisy-le-Roi - Vitry-sur-Seine -Joinville-le-Pont), suburbs located south of Paris.

Las Montana was also a leader in the group that suffered from many legal problems as many of its members went to prison on certain charges.

The diverse group concentrated on Hip-Hop, but there were also breakdancers like Mokobé, Selim du 94 and Teddy Corona, graffiti artists like AP and Douma, backers like Las Montana, Mamad, Rocco, OGB, beatboxers like Mista Flo and DJs like DJ Mehdi and DJ Mosko.

Some members had big commercial success like 113 and Rohff and Intouchable (with Dry, Demon One and Mamad) before Mamad's death in 2003 just after the collective joint album La cerise sur le ghetto, which marked the release of music videos for "Pour ceux" [1] and "Balance" [2].
