She's the Boss is the solo album debut by The Rolling Stones frontman Mick Jagger released in 1985. When the Stones signed with CBS Records in 1983, one of the options available to them was for individual projects, and Jagger—ready to turn his back on his friends after recording exclusively with them for 20 years—eagerly began working on She's the Boss.

Following the release of Undercover, Jagger began composing material for his first solo project, sanctioning the help of various musician friends in the studio when recording began in May 1984. Of those involved were Pete Townshend, Jeff Beck, Carlos Alomar, and Herbie Hancock, while Jagger would share production duties with Bill Laswell and Nile Rodgers.

Keith Richards, Jagger's longtime musical partner in the Rolling Stones, was not pleased that Jagger was pursuing solo work, feeling that their band should be each others' first priority. The growing friction between both musicians would erupt publicly in 1986, before they resolved their differences a couple of years later.

Boss may refer to:

Sir Michael Philip "Mick" Jagger, (born 26 July 1943) is an English musician, singer, songwriter and actor, best known as the lead vocalist and a founder member of The Rolling Stones.

Jagger's career has spanned over fifty years. Allmusic has described Jagger as "one of the most popular and influential frontmen in the history of rock & roll". His distinctive voice and performance, along with Keith Richards' guitar style, have been the trademark of The Rolling Stones throughout the career of the band. In 1989, he was inducted into the Rock and Roll Hall of Fame with The Rolling Stones.

Jagger gained much press notoriety for admitted drug use and romantic involvements, and was often portrayed as a counterculture figure. In the late 1960s Jagger began acting in films (starting with Performance and Ned Kelly), to mixed reception. In 1985, Jagger released his first solo album, She's the Boss, and was knighted in 2003. In early 2009, he joined the eclectic supergroup SuperHeavy.

Jagger was born into a middle class family at Livingstone Hospital, in Dartford, Kent, England. His father, Basil Fanshawe ("Joe") Jagger (13 April 1913 – 11 November 2006), and his grandfather David Ernest Jagger were both teachers. His mother, Eva Ensley Mary (née Scutts; 6 April 1913 – 18 May 2000), born in New South Wales, Australia, was a hairdresser and an active member of the Conservative Party. Jagger is the elder of two sons (his brother Chris Jagger was born on 19 December 1947) and was raised to follow in his father's career path.
