"You Don't Have to Worry" is a song by American R&B recording artist Mary J. Blige. The song was written for her by Kenny Greene, Edward Ferrell, Darrin Whittington and Kevin Kornegay, and is produced by former Bad Boy rapper Craig Mack for the soundtrack of the film Who's the Man? (1993). The song contains an uncredited portion of the 1988 hip-hop cut, "The Vapors" as performed by American beat-boxer/rapper Biz Markie, which in turn samples the 1974 number-one R&B hit, "Papa Don't Take No Mess", as performed by James Brown. The original version appears on the film's soundtrack. This version performed modestly on the US Billboard Hot 100, peaking at number sixty-three, and reaching number eleven on the R&B singles chart. It is one out of two singles to be released on the soundtrack (the other being "Party and Bullshit" by The Notorious B.I.G.).

The official remix version (entitled as "You Don't Have to Worry (Remix Main with Rap)") appears on Blige's remix album, What's the 411? Remix, whereas the remix version contains a portion of Lou Donaldson's "Ode to Billie Joe". This version is produced by Sean "Puffy" Combs and Tony Dofat.

The music video, which was directed by F. Gary Gray was filmed at various locations in New York City in the summer of 1993, with Mary performing in a jersey with a New York Yankees cap and baggy jeans, and scenes features Mary wearing an all denim suit with matching boots performing on top of a car in front of a large crowd, as well her wearing an orange jacket. The song's original version which appears in the video, has a slightly alternate difference towards the one on the soundtrack, Blige's vocals throughout the song is multitracked, and the backing vocals are omitted. However, on the soundtrack, her vocals are not multitracked and the chorus/hook is featured throughout. In 2005, the song was later interpolated on Blige's song, "MJB da MVP" from her hugely successful seventh album The Breakthrough.
