Jeffrey Allen Townes is an American record producer, DJ, actor and comedian who is best known for his friendship and collaboration with Will Smith as DJ Jazzy Jeff & The Fresh Prince.

Early on, he developed a reputation and a following as a school and Block party DJ.

He was ten years old when he first became interested in being a DJ. He told author Paul Stenning, "At summer time block parties I wouldn't be the one dancing, I was sat where the DJ was set up, watching him. Even when I would go to other block parties in other neighborhoods I was still infatuated with the DJ. He was the guy that played music that everyone in the neighborhood loved. You might not have known his face, you might not have known his name but he was the guy that made everyone move."

He took the stage name DJ Jazzy Jeff and was one half of the duo DJ Jazzy Jeff & The Fresh Prince along with Will Smith. The group received the first Grammy Award for Best Rap Performance in 1989 for "Parents Just Don't Understand", though their most successful single was "Summertime" which earned the group their second Grammy and peaked at number 4 on the Billboard Hot 100.

When Smith branched out into television with the sitcom The Fresh Prince of Bel-Air, Jazzy Jeff played a recurring character named Jazz, Smith's best friend on the show. In the early seasons, the two characters always greeted each other with their signature handshake (swinging mid-five, point-back, snap with both characters saying "Pssh!"). A recurring joke throughout the show's run involved the character being physically ejected from the house by Uncle Phil (James Avery), using the same footage for comedic effect.

One of the first records DJ Jazzy Jeff ever appeared on was with The Korner Boyz (Street Artz Records) "Bust The Move and The Soga of Roxanne", which featured legendary Philadelphia rapper, MC Parry P and Grand Tone. The Instrumental was called "Jazzy Jeff Scratch" (1985). DJ Jazzy Jeff along with DJ Cash Money is credited with making the transformer scratch famous.

As a duo, DJ Jazzy Jeff & The Fresh Prince had several gold and platinum-selling albums and singles in the late 1980s and early 1990s, earning them the first rap Grammy Award ever presented in 1989 for "Parents Just Don't Understand."

At the time of winning the Grammy Award DJ Jazzy Jeff came home crying as he had just $500 in the bank.

They also won a second Grammy for "Summertime".

After DJ Jazzy Jeff & the Fresh Prince broke up, Townes went on to become a prominent R&B, soul, and neo soul record producer, establishing the A Touch of Jazz production company in his native Philadelphia. Among the artists that Jazzy Jeff has helped develop are Eric Roberson, Jill Scott, Musiq Soulchild, Eminem, The Roots, Jewel, Darius Rucker, Talib Kweli, Floetry, Rhymefest, and many more. Even though he separated from Will Smith as a music partner, they are still friends, and occasionally work together.

Some songs by Smith were produced by Townes (including “Here He Comes"), and he has performed on some songs by Smith such as "So Fresh" and "Potnas." In addition, he appeared in several of Smith's music videos such as "Will2K" and "Freakin' It". On some occasions, he made appearances with Smith at live concerts, producing DJ scratches. On July 2, 2005, DJ Jazzy Jeff performed with Smith at the Live 8 concert in Philadelphia. Moreover, Smith acknowledges him in his music such as "Comin' To The Stage" from the album Lost and Found and "Potnas" from his album Willennium.

His 2007 release The Return of the Magnificent featured numerous collaborations with old school and new school artists including CL Smooth, Big Daddy Kane, Pos from De La Soul, Method Man, Peedi Peedi (a remake of Brand New Funk), Rhymefest, and Raheem DeVaughn. In 2007, he appeared with Rhymefest in a video directed by Konee Rok, in which he makes music in his home recording studio with Rhymefest.
