DJ Jazzy Jeff & the Fresh Prince were an American hip hop duo from West Philadelphia, Pennsylvania, consisting of rapper Will Smith and disc jockey Jeff Townes. Active full time from 1986 to 1994 and occasionally thereafter, the duo became just the third rap group in recorded history to receive platinum certification, after Run-DMC and the Beastie Boys. The group received the first Grammy Award for Best Rap Performance in 1989 for "Parents Just Don't Understand" (1988), though their most successful single was "Summertime" (1991), which earned the group their second Grammy and peaked at number 4 on the Billboard Hot 100. Will Smith and Jeff Townes have remained close friends and claim they never split up, having made songs together under Smith's solo performer credit. DJ Jazzy Jeff & the Fresh Prince have sold over 5.5 million albums in the US. They performed together as recently as November 2023.

West Philadelphia, nicknamed West Philly, is a section of the city of Philadelphia. Although there are no officially defined boundaries, it is generally considered to reach from the western shore of the Schuylkill River, to City Avenue to the northwest, Cobbs Creek to the southwest, and the SEPTA Media/Wawa Line to the south. An alternate definition includes all city land west of the Schuylkill; this would also include Southwest Philadelphia and its neighborhoods. The eastern side of West Philadelphia is also known as University City.
