"6 Foot 7 Foot" (also styled as "6'7") is a song by American rapper Lil Wayne featuring label mate Cory Gunz. It is taken from Wayne's ninth album, Tha Carter IV (2011). It was officially released on iTunes on December 16, 2010. It was produced by "A Milli" producer Bangladesh. The song samples "Day-O (The Banana Boat Song)" by Harry Belafonte (particularly, as the title implies, the lyric "6 foot, 7 foot, 8 foot bunch".)

"6 Foot 7 Foot" is the first single off The Carter IV. The track is the first single Lil Wayne has recorded since his release from prison on November 4, 2010, though it's the second song on which he has appeared since his prison release, after the final version of Birdman's single "Fire Flame", on which he had 2 verses. In the original version of the single, Lil Wayne is absent due to his prison sentence. Before the song was officially released, Shade 45's DJ Drama interviewed Lil Wayne and he talked about the single. He said "It's a monster," and "Hopefully, it shows people where I'm at lyrically." Mack Maine, president of Young Money and fellow labelmate, called it "A Milli on steroids." The track was originally intended for rapper T.I., but the Atlantic records manager who also co-manages Lil Wayne, decided Lil Wayne would be a better fit, reuniting Lil Wayne and producer Bangladesh for the first time since "A Milli" after the royalty dispute between Bangladesh and Cash Money on that song. It is the second time the trio (Lil Wayne, Cory Gunz, Bangladesh) have worked together, after 2008's "A Milli" (though Cory Gunz was not on the final version of that song). Lil Wayne performed the song on Saturday Night Live and New Year's Eve with Carson Daly. He also performed it on 106 & Party Cash Money Young Money New Years.
