Michael John Kells "Mick" Fleetwood is a British-born musician best known for his role as the drummer and namesake of the blues/rock and roll band Fleetwood Mac. His surname, combined with that of John McVie, was the inspiration for the name of the originally Peter Green-led Fleetwood Mac.

Aside from his work as a drummer, he also helped form the different incarnations of his band Fleetwood Mac, and is the sole member to stay with the band through its ever-changing lineup. In 1974, he met and invited Lindsey Buckingham and Stevie Nicks to join Fleetwood Mac. Although Buckingham and Nicks deserve credit for contributing to much of Fleetwood Mac's later commercial success, Fleetwood's determination to keep the band together was essential to Fleetwood Mac's longevity as a band and to their lasting international success.
