The first of three sons born in Adelaide,Unley to Martin and Jeanne (nee Richardson), Chappell was steeped in the game from an early age. His father was a noted Adelaide grade cricketer who put a bat in his hands as soon as he could walk, and his maternal grandfather was famous all-round sportsman Vic Richardson, who captained Australia at the end of a nineteen-Test career. Chappell was given weekly batting lessons from the age of five, as were younger brothers Greg and Trevor, who both also went on to play for Australia.  Chappell grew up in the beachside suburb of Glenelg and attended the local St Leonard's Primary School where he played his first competitive match at the age of seven. He was later selected for the South Australian state schoolboys team. He then enrolled at Prince Alfred College, a private secondary school noted for producing many Test cricketers, including the Australian captains Joe Darling and Clem Hill. His other sporting pursuits included Australian football and baseball: Chappell's performances for South Australia in the Claxton Shield won him All-Australian selection in 1964 and 1966 as a catcher. He credits Vic Richardson, who had represented both SA and Australia in baseball during the 1920s, for his love of the sport. At the age of 18, his form in grade cricket for Glenelg led to his first-class debut for South Australia (SA) against Tasmania in early 1962. Chappell replaced West Indian Gary Sobers who was selected for a Test match in the Caribbean.  The aggressive style of Sobers and South-Australia captain Les Favell heavily influenced Chappell during his formative years in senior cricket. In 1962-63, Chappell made his initial first-class century against a New South Wales team led by Australian captain Richie Benaud, who was bemused by the young batsman's habit of gritting his teeth as he faced up; to Benaud, it looked as if he was grinning. Chappell spent the northern summer of 1963 as a professional in England's Lancashire League with Ramsbottom and played a single first-class match for Lancashire against Cambridge University.
