David Walker (born January 25, 1945, in Walsall, Staffordshire, England) is a singer and guitarist for a number of bands; notably Savoy Brown and Fleetwood Mac. He shortened his name to Dave Walker. He started his career in the early 1960s with a Brumbeat R & B band called The Redcaps; and he worked right up until the start of the twenty-first century, with Donovan's Brain.

Other bands he played in included Beckett, Idle Race, Hungry Fighter, Raven, Mistress and Black Sabbath.

Walker was raised by his strict grandmother in a household where rock and roll was not allowed to be watched on television. His first experience with public singing came at a very young age at a Methodist church, where Dave volunteered to sing "Away in a Manger". As teens, Dave and his brother Mick would form a "backyard" skiffle group playing the odd wedding and youth gathering.
