The West Indian cricket team in England in 1963 played 30 first-class matches of which they won 15, lost 2 and drew 13. West Indies played five Tests and won the series against England by three matches to one, with one game drawn.
As a result of the great success of this series, England's future home Test programme was revised so that West Indies could return in 1966, much earlier than originally planned. This was done by introducing "twin tours", in which two countries would each play three Tests against England in the course of a season.

Match drawn: West Indies 301 and 229; England 297 and 228-9
This match had a very exciting climax. When time ran out, England were six runs short of the 234 that they needed to win. The ninth wicket fell when Derek Shackleton was run out from the fourth ball of the final over. Colin Cowdrey had had his left arm broken earlier in the innings, and had retired hurt. Now he reappeared, with his arm in plaster. Luckily for him, and for England, he was not required to face a ball, David Allen playing out the remaining two deliveries.
