James "Jem" Grundy (5 March 1824 in New Radford, Nottingham – 24 November 1873 in Carrington, Nottingham) was an English cricketer during the game's roundarm era. He was one of the notable bowlers of the 1850s and was frequently among the leading wicket-takers. He bowled right-arm fast roundarm and is known to have occasionally used fast underarm deliveries, but he is said to have varied his pace. He batted right-handed and was an occasional wicket-keeper. In 1857, he became the first person to be given out handled the ball.
