Ronald Winston Boon (11 June 1909 – 3 August 1998) was an international rugby union wing for Wales who played club rugby for Cardiff. Boon possessed a tremendous self-confidence in his own ability and this was reflected in his nickname Cocky. Boon was a quick runner, representing Wales at the 220-yard sprint, and was an excellent drop kicker. He is best known in Welsh rugby as the man who scored all seven points in 1933 against England to end the 'Twickenham bogey', and along with Jack Morley is seen as one of the greatest Welsh wings since the country's first Golden Era of rugby.
