"It's a Demo" is the 1986 debut single by American hip hop duo Kool G Rap & DJ Polo.

Originally a non-album single with "I'm Fly" as a B-side, a remix of the track was featured on the duo's 1989 album Road to the Riches and later on the compilation albums Killer Kuts (1994), The Best of Cold Chillin' (2000), Greatest Hits (2002) and Street Stories: The Best of Kool G Rap & DJ Polo (2013).

The song was recorded at Marley Marl's home studio in Queensbridge, Queens, New York City and was originally indented to be a demo track.

He's just eager to hear me because of his boy Polo blowing me up like, "Yo, I got this young kid that's crazy!"
