Nijinsky was a Canadian-bred, Irish-trained champion Thoroughbred racehorse and sire. He was the outstanding two-year-old in Europe in 1969 when he was unbeaten in five races. In the following season, he became the first horse for thirty-five years to win the English Triple Crown, a feat that has not been repeated as of 2023. He is regarded as one of the greatest European flat racehorses of the 20th century.
