Michael John Kells Fleetwood was born in Redruth, second child to John Joseph Kells Fleetwood and Bridget Maureen (nee Brereton) Fleetwood. His elder sister Susan Fleetwood, who died of cancer in 1995, became an actress. In early childhood Fleetwood and his family followed his father, a Royal Air Force fighter pilot, to Egypt. After about six years, they moved to Norway where his father was posted on a NATO deployment.

Fleetwood also led a number of side projects. 1981's The Visitor produced by Richard Dashut, featured heavy African stylistics and a rerecording of "Rattlesnake Shake" with Peter Green. The song "You weren't in love" was a hit in Brazil because of the Soap-opera Brilliant. In 1983 he formed Mick Fleetwood's Zoo and recorded I'm Not Me. The album featured a minor hit, "I Want You Back", and a cover version of the Beach Boys' "Angel Come Home". A later version of the group featured Bekka Bramlett on vocals and recorded 1991's Shaking the Cage. Fleetwood released Something Big in 2004 with The Mick Fleetwood Band, and his most recent album is Blue Again!, appearing in October 2008 with the Mick Fleetwood Blues Band touring to support it, interspersed with the Unleashed tour of Fleetwood Mac.  He has played drums on many of his bandmates' solo records, including Law and Order, where he played on the album's biggest hit, Trouble. Other albums include French Kiss, Three Hearts, The Wild Heart, Christine McVie, Try Me, Under the Skin, Gift of Screws, and In Your Dreams. In 2007 he was featured on drums for the song "God" along with Jack's Mannequin in the Pop album Instant Karma: The Amnesty International Campaign to Save Darfur, a collection of covers of John Lennon songs.  In literature, Fleetwood co-authored Fleetwood - My Life and Adventures with Fleetwood Mac with writer Stephen Davis, published by William Morrow & Co. in 1990. In the book he candidly discussed his experiences with other musicians including Eric Clapton, members of The Rolling Stones, Led Zeppelin, as well as the affair with Stevie Nicks and his addiction to cocaine and his personal bankruptcy. Reception was mixed. Robert Waddell of the New York Times described the piece as "a blithe, slapdash memoir." The Los Angeles Times's Steve Hochman noted that "Fleetwood tells the story as if he was sitting in your living room, which is good for the intimacy of the tale, but bad for the rambling, sometimes redundant telling." Hochman did acknowledge that Fleetwood was "one of rock's more colorful characters."  Fleetwood has a secondary career as a TV and film actor, usually in minor parts. His roles in this field have included a resistance leader in The Running Man and as a guest alien in the Star Trek: The Next Generation episode "Manhunt". Fleetwood co-hosted the 1989 BRIT Awards, which contained numerous gaffes and flubbed lines. In the wake of this public mishap, the BRIT Awards were pre-recorded for the next 18 years until 2007; the awards are now again broadcast live to the British public. Fleetwood and his third wife, Lynn, had twin daughters (Ruby and Tessa) who were born in 2002 he also became a U.S. citizen on 22 November. Fleetwood filed for divorce from Lynn in 2013.
