Black Friday is a mixtape by Lil' Kim. The cover, featuring a decapitated Nicki Minaj, was a fan's idea. The mixtape's title/title track is a play on Minaj's debut album Pink Friday as well as being a reference to Friday the 13th, also known as Black Friday, as heard in the lyric "...im turning Pink Friday to Friday the 13th".

Furthermore Lil' Kim has stated that Nicki Minaj had been "swagger jacking" her. The mixtape was sold on PayPal for $9.99.
Black Friday received negative reviews from music critics. Kid Fury of Vibe described its content as "tragic shit" and commented that the mixtape "lacks consistency, edge, and originality".Slant Magazine's Huw Jones gave it one-and-a-half out of five stars and felt that its production lacks "originality". Jones also panned Lil Kim's lyrics and disses towards Minaj as "inane", writing that "there are some pert jabs dotted among the tactless insults, but for the most part, it's a senseless rant". Kazeem Famuyide of The Source wrote that "I know it's a dated name ... but I don't think it’s that crazy as far as appealing to her hardcore fan base". Jozen Cummings of XXL wrote facetiously, "It's not that we refuse to pay for music, we'd just much rather have an option to not do it. If you force any price tag on us without giving us a decent amount of free music to sample from, we're scoffing at that $9.99".
