Robert George Dylan Willis (30 May 1949 – 4 December 2019) was an English cricketer, who represented England between 1971 and 1984. A right-handed fast bowler, Willis is regarded by many as one of the greatest fast bowlers of all time. He was a part of the English squad that finished as runners-up at the 1979 Cricket World Cup.
As of June 2023 he was England's fourth-highest wicket-taker, behind James Anderson, Stuart Broad and Ian Botham. Willis took 899 first-class wickets overall, although from 1975 onwards he bowled with constant pain, having had surgery on both knees. He nevertheless continued to find success, taking a Test career-best eight wickets for 43 runs in the 1981 Ashes series against Australia, one of the all-time best Test bowling performances.
