Nathaniel Thomas Wilson (born July 20, 1968), better known by his stage names Kool G Rap (or simply G Rap, and originally Kool Genius of Rap) is an American rapper, from the Corona neighborhood of Queens, New York City. He began his career in the mid-1980s as one half of the group Kool G Rap & DJ Polo and as a member of the Juice Crew. He is often cited as one of the most influential and skilled MCs of all time as he is a pioneer of mafioso rap/street/hardcore content and multisyllabic rhyming. On his album The Giancana Story, he stated that the "G" in his name stands for "Giancana" (after the mobster Sam Giancana), but on other occasions he's stated that it stands for "Genius".

He has also been cited as a major influence to some of hip-hop's most critically acclaimed figures such as Eminem, Nas, Jay-Z, Big Pun, RZA and more.

Wilson grew up in the poverty-ridden streets of Corona Queens, New York with legendary producer Eric B. In an interview with The Source he stated;

Growing up in Corona was like a little Harlem, it wasn't that hard for a nigga to be influenced by the street life type of mentality. I was like 15 years old, Ma dukes couldn't dress a nigga no more and at that age you want a little money in your pocket. That's what gets us all, material possessions. A nigga got caught up in that mentality. Nigga started selling drugs at a certain point, and all that shit, it's what was goin' on in the streets ... eventually all my friends got smoked. Everybody was droppin'. All my friends started packing burners everyday, we was wild shorties.
