Dennis Keith Lillee is a former Australian cricketer, described as the most outstanding fast bowler of his generation.

In the Ashes tour of England in 1972, he was the outstanding bowler on either team, taking 31 wickets at an average of 17.67. This earned him selection as one of Wisden's Five Cricketers of the Year for 1973.Following a period of recuperation from stress fracture he returned to Test cricket for the Ashes series of 1974 and was paired with New South Wales fast bowler Jeff Thomson to form one of the most effective opening bowling combinations in Test cricket.
He was announced as one of the WSC players in May 1977. In nine "Supertests" during 1978–79, Lillee captured 46 wickets at 22.5 average. Against New Zealand and India in 1980–81, Lillee took 37 wickets in six Tests and was the leading bowler in the World Series Cup for the second successive season. By the time of his retirement from international cricket in 1984 he had become the then world record holder for most Test wickets (355). On 17 December 2009, Lillee was inducted into the ICC Cricket Hall of Fame.
