Graham Douglas McKenzie (born 24 June 1941) – commonly known as "Garth", after the comic strip hero – is an Australian cricketer who played for Western Australia (1960–74), Leicestershire (1969–75), Transvaal (1979–80) and Australia (1961–71) and was a Wisden Cricketer of the Year in 1965.
He succeeded Alan Davidson as Australia's premier fast bowler and was in turn succeeded by Dennis Lillee, playing with both at either end of his career.
McKenzie was particularly noted for his muscular physique (hence his nickname) and ability to take wickets on good batting tracks.
His father Eric McKenzie and uncle Douglas McKenzie played cricket for Western Australia and Garth was chosen for the Ashes tour of England in 1961 aged only 19.
He made his debut in the Second Test at Lord's, where his 5/37 (including the last three wickets in 12 balls) wrapped up the England innings to give Australia a 5 wicket victory.
