Sir Clyde Leopold Walcott KA, GCM, OBE (17 January 1926 – 26 August 2006) was a West Indian cricketer.

Walcott was a member of the "three W's", the other two being Everton Weekes and Frank Worrell: all were very successful batsmen from Barbados, born within a short distance of each other in Bridgetown, Barbados in a period of 18 months from August 1924 to January 1926; all made their Test cricket debut against England in 1948.

He made his first impression in February 1946, when, on a matting wicket, he scored 314 not out for Barbados against Trinidad as part of an unbroken stand of 574 for the fourth wicket with schoolfriend Frank Worrell (255 not out), setting a world record for any partnership in first-class cricket that remains a record in the West Indies.

From a crouched stance, he was particularly strong off the back foot, and quick to cut, drive or pull.

Despite his height, Walcott also kept wicket for his country in his first 15 Tests, his versatility enabling to retain his position in the side despite some poor batting performances in his first few matches.

By the time a back injury forced him to relinquish the gloves, his batting had improved sufficiently to enable him to keep his place.

In those roles he engineered huge strides in the development of cricket among poor, mainly Indo-Guyanese plantation workers, widening access to the game, upgrading facilities, organising clubs and competitions and improving coaching techniques.

This led directly to the emergence of a number of world-class Indo-Guyanese cricketers – including Rohan Kanhai and Joe Solomon – from an area of the Caribbean that had hitherto been unknown and overlooked as a source of talent.

Walcott's biographer, Peter Mason, argues in Clyde Walcott: Statesman of West Indies Cricket that his work in British Guiana "revitalised the colony’s fortunes in the regional game, while helping to develop an array of brilliant new Guyanese players who became the backbone of West Indies success for years to come".

[3] Simultaneously, says Mason, "he stimulated new self-worth and a more tangible Caribbean identity among the Indian population of the sugar estates on which he worked",[4] while also doing much to enhance living and working conditions as part of the Sugar Producers' Association’s long-running programme of improvements.
