"Business" is a song by American rapper Eminem from his fourth studio album The Eminem Show (2002). "Business" was released as the final single from The Eminem Show in July 2003 but it was not released as an official single in the United States.

"Business" is a hip hop song of four minutes and eleven seconds in length. It sees Eminem comparing himself and Dr. Dre, the song's producer, to fictional crime-fighting duo Batman and Robin, a comparison first explored in the music video for the previous Eminem single "Without Me". The lyrics are backed by a "cartoonish" beat: one of several Dr. Dre productions on The Eminem Show which, according to CultureDose writer Marty Brown, affords Eminem a "perfect sound-scape" to inspire emotions in the listener, calling the beat "a launchpad equally effective for humor or anger". Writing for Pitchfork Media, Ethan P. noted the "cartoonish" production to be similar in style to several of Eminem's early singles, claiming it to be fitting to the Batman and Robin theme on "Business", but noted that "this time he's actually talking about Batman and Robin!!". DX Magazine editor J-23 called this "classic" with Dre beats. Kris Ex On "Business": "Em names himself the gatekeeper of hip-hop and obliquely claims to be the best rapper alive: 'The flow's too wet/Nobody close to it/Nobody says it, but everybody knows the shit.'"
