"Jenny from the Block" is a song by American singer Jennifer Lopez, which features American rappers Jadakiss and Styles P, both members of the LOX. It was released by Epic Records on September 26, 2002, as the lead single from her third studio album, This Is Me... Then (2002). The song, first leaked online, was written by Lopez, Troy Oliver, Mr. Deyo, Samuel Barnes, and Jean Claude Olivier. Cory Rooney, Olivier, Barnes, and Oliver produced the song. Another version of the track features solely Lopez, which was part of the Brazilian edition of the album. The track is an R&B and old school hip hop song which makes use of multiple music samples, including from songs such as 20th Century Steel Band's "Heaven and Hell Is on Earth" (1975), Boogie Down Productions' "South Bronx" (1987), and "Hi-Jack" by Enoch Light. Lyrically, the track centers around Lopez paying homage to her roots in the Bronx and professing that fame has not changed her, while celebrating her success.
