Derek Leslie Underwood MBE was an English international cricketer. In retirement he became president of the Marylebone Cricket Club in 2008.
Through much of his career, Underwood was regarded as one of the best bowlers in Test cricket. Although classified as a slow left-arm orthodox spin bowler, Underwood bowled at around medium pace. He was often unplayable on seaming English wickets, particularly sticky wickets, earning his nickname 'Deadly'.
