Lead Pipe is the second studio album by American rapper Grand Daddy I.U. from Queens, New York. It was released on June 21, 1994 through Cold Chillin'/Epic Street. The entire album (with the exception of "Blast a New Asshole") was produced by Grand Daddy I.U. and Kay Cee.
Despite being released on a major label, the album was a commercial failure, only reaching number 88 on the Billboard Top R&B/Hip-Hop Albums. Following the album, Grand Daddy I.U. appeared on Big L's 1995 album, Lifestylez ov da Poor & Dangerous and then went on a 12-year hiatus before returning in 2007 with his third studio album, Stick to the Script.
