, Malcolm Denzil Marshall (18 April 1958 - 4 November 1999) was a West Indian cricketer. Primarily a fast bowler, Marshall is regarded as one of the finest and fastest pacemen ever to have played Test cricket. His Test bowling average of 20.94 is the best of anyone who has taken 200 or more wickets. He achieved his bowling success despite being, by the standards of other fast bowlers, a short man - he stood at 5 feet 11 inches (1.80 m), while most of the great quicks have been well above 6 feet (1.8 m) and many great West Indian fast bowlers, such as Joel Garner, Curtly Ambrose and Courtney Walsh, were 6 feet 6 inches (1.98 m) or above.

Marshall was born in Bridgetown, Barbados. His father, Denzil DeCoster Edghill was also an outstanding cricketer who played for Kingspark cricket club in St. Philip the son of Claudine (nee Edghill) and Guirdwood Ifill, was a policeman; he died in a traffic accident when Marshall was one year old. His mother was Eleanor (nee Welch). Malcolm had three half-brothers and three half-sisters. He grew up in the parish of Saint Michael, Barbados and was educated at St Giles Boys' School from 1963 to 1969 and then at Parkinson Comprehensive from 1969 to 1973.  He was partly taught cricket by his grandfather, who helped to bring him up after his father's death. He played cricket for the Banks Brewery team from 1976. His first representative match was a 40-over affair for West Indies Young Cricketers against their English equivalents at Pointe-a-Pierre, Trinidad and Tobago in August 1976. He made nought and his eight overs disappeared for 53 runs.  Marshall's initial senior appearance was a Geddes Grant/Harrison Line Trophy (List A) match for Barbados on 13 February 1978; again he made a duck and did not take a wicket. Four days later, he made his first-class debut against Jamaica, and whilst he failed to score runs, he claimed 6-77 in the Jamaican first innings. On the back of this single first-class appearance he was selected to tour India in 1978/79, many first-choice West Indian stars being unavailable having committed themselves to playing World Series Cricket. Marshall heard of his selection on the radio while working in the storeroom at Banks Brewery and later claimed he did not know where India was.
