Boucher (1969 – after 1986), was an American-bred, Irish-trained Thoroughbred racehorse and sire. In Ireland he won the Beresford Stakes as a two-year-old in 1971 and went on to win the Nijinsky Stakes and the Desmond Stakes in 1972. In September 1972 he was sent to England where he won the St. Leger Stakes at Doncaster. At the end of the season he was retired to stand as a stallion in Australia, where he had some success as a sire of winners.
