MC4 (abbreviation for Mac & Cheese 4) is the thirteenth mixtape by American rapper French Montana. MC4 was originally intended to be his second studio album. It was scheduled to be released on October 14, 2016, by Coke Boys Records, Bad Boy Records and Epic Records. However, the album's release was canceled after Target unofficially released the album on CD, on its original release date, August 19, 2016, two months before the album was set to release, which was later leaked online in its entirety. Subsequently, the album was heavily bootlegged. It is the fourth installment in the Mac & Cheese series, and was intended to be the first of the series to be released as an album. On November 5, 2016, Montana unexpectedly released the album as a mixtape instead and premiered it on Canadian singer Drake's Beats 1 radio show, OVO Sound, later that night.

The project notably includes guest appearances from Kanye West, Miguel, Drake, Jeezy, ASAP Rocky, Kodak Black, Nas and Chinx. The album's production was handled by The Mekanics, Harry Fraud, Murda Beatz, Detail, DJ Khalil, and The Alchemist, among others.
