Barbershop 2: Back in Business is a 2004 American comedy-drama film directed by Kevin Rodney Sullivan and released by Metro-Goldwyn-Mayer Pictures on February 6, 2004. A sequel to 2002's Barbershop and the second film in the Barbershop film series, also from State Street producing team Robert Teitel and George Tillman Jr., Barbershop 2 deals with the impact of gentrification on the reputation and livelihood of a long-standing south Chicago barbershop. Ice Cube, Cedric the Entertainer, Sean Patrick Thomas, Eve, and several more actors reprise their roles from the first Barbershop film. However, a few of the original film's actors including Tom Wright and Jazsmin Lewis return with smaller roles.

Released theatrically by Metro-Goldwyn-Mayer Pictures on February 6, 2004, Barbershop 2 received generally positive reviews from critics and was a box office success, grossing $66 million worldwide against a production budget of $18–30 million.

Barbershop 2 also features what is billed as a "special appearance" by Queen Latifah, who starred in a spin-off, Beauty Shop which was released in March 2005.
