Giacometti (1971 – after 1985) was an Irish-bred, British-trained Thoroughbred racehorse and sire. In 1974 he became the fourth horse since the Second World War to be placed in all three legs of the British Triple Crown. Regarded by his stable as a potential "world beater", he was unbeaten as a two-year-old, winning his first race by at least twelve lengths and then taking the Gimcrack Stakes and the Champagne Stakes. As a three-year-old he finished second in the 2000 Guineas, third in the Epsom Derby and second in the St Leger before winning the Champion Stakes. After two defeats in 1975 he was retired to stud in the United States where he made very little impact as a breeding stallion.
