Kool G Rap (born Nathaniel Wilson July 20, 1968) is an American hardcore Mafioso rapper from Queens, New York. He began his career with the Juice Crew in the 1980s but achieved little commercial success.

G Rap began working with DJ Polo in 1986, releasing several underground hit singles including "It's a Demo"/"I'm Fly", "Streets of New York" and "Road to the Riches". G Rap grew in popularity but never crossed over like Biz Markie or Big Daddy Kane, both also members of the Juice Crew.

G Rap began a solo career in the mid-1990s, released 4,5,6. This and subsequent LPs saw little attention from critics or consumers, and G Rap began collaborating with others. Signing to Rawkus Records, G Rap launched a comeback with 2002's The Giancana Story. The album was well-received.
