Dennis George A'Court (born 27 July 1937) is a former Welsh-born cricketer.
He was a right-handed batsman and a right-arm medium-fast bowler who played first-class cricket for Gloucestershire between 1960 and 1963.
He was born in Markham in Monmouthshire, a former mining village.
He took 145 first-class wickets, with a best of 6 for 25 against the South African tourists in 1960: Wisden noted that he "shocked the South Africans with his accuracy, liveliness, and disconcerting swing and movement of the ball".
He took five wickets in an innings on five occasions.
