"Hit 'Em Up" is a diss song by rap artist 2Pac featuring his group the Outlawz. It is the B-side to the single "How Do U Want It", released on June 4, 1996. The song's lyrics contain vicious insults to several East Coast rappers, chief among them, Shakur's former friend turned rival, The Notorious B.I.G., also known as Biggie Smalls.

"Hit 'Em Up" was written and recorded in Buena Vista Studios in Buena Vista, Virginia in May 1996. For the song, Shakur recruited the members of the former group Dramacydal whom he had worked with previously, and was eager to work with again. Together, the rappers (along with other associates) formed the original lineup of the Outlawz. The first and third verses are performed by Shakur, while the second verse is performed by Hussein Fatal, the fourth by Kadafi and the fifth by E.D.I. Mean.  The ferocity of Shakur's raging vocals, as said by long-time collaborator and producer of "Hit 'Em Up" Johnny "J", was entirely authentic. He explained that Shakur was initially fueled by his anger against Biggie and Bad Boy Records for the belief that they had a role in the November 30, 1994 ambush and attack on Shakur. He claimed that Biggie and his crew knew of his shooting and wanted him dead. Shakur used this fury, which Johnny "J" described as "superhuman", to attack Biggie and other East Coast rappers. Johnny "J" also stated that he had never seen Shakur so angry and that the words he rapped were in no way an act, describing the recording process as the most "hard-core he had ever done." Although he was very happy with the work he had put into it and the resulting song, Johnny "J" went on to say that he had no desire to work on anything of that magnitude again.  Shakur was also enraged by Biggie's release of "Who Shot Ya?" provocatively only months after the shooting incident, and although it did not directly involve Shakur's name, he believed it was directed towards him, but it was not. Shakur admitted to releasing "Hit 'Em Up" as a response to "Who Shot Ya?" In a Vibe interview, the rapper called out Sean "Puffy" Combs and Biggie Smalls and accused both of them for setting him up, or obtaining knowledge of the attack, and not cautioning him. He also singled out business men James Rosemond ("Jimmy Henchman"), and Jacques Agnant ("Haitian Jack") of orchestrating the assault. Shakur announced the names of his ostensible conspirators to Kevin Powell, a journalist for Vibe; however, to mask their true identities, Vibe referred to Henchman as "Booker," and Jack as "Nigel" in the published interview. Persons familiar with the interview say they used different names after the magazine received threats from Henchman. A former Vibe editor denied receiving threats, but neglected to explain why the magazine substituted aliases for Henchman and Haitian Jack.  Henchman promised Shakur $7,000 to duo with Lil Shawn, a rapper whom the business man represented at that time. In a 2008 article by Philips, Henchman was implicated in organizing the assault, and in 2012 by his long-time friend Dexter Isaac, who confessed to attacking Shakur on Henchman's orders. He was confirmed as a source for Philip's earlier story and in Henchman's own confession according to prosecutors at his 2012 trial.
