Reginald Thomas David Perks (4 October 1911 – 22 November 1977) was an English cricketer who played in two Test matches in 1939, and was the mainstay of Worcestershire's bowling for a long period from the middle 1930s until the middle 1950s. He was also an aggressive left-handed tail-end slogger, who frequently hit up thirty runs in twenty or so minutes, and on three occasions hit three sixes off consecutive balls. His highest first-class score of 75 against Nottinghamshire at Trent Bridge in 1938 took just thirty minutes. He does, however, hold the world record for the most ducks in a first-class career, with 156.
