The Grey Gatsby is an Irish-bred racehorse who was trained in Britain and Ireland. In 2014 he established himself as one of the best colts of his generation in Europe by winning the Dante Stakes and the Prix du Jockey Club before defeating the dual Derby winner Australia in the Irish Champion Stakes. At the end of the year he was rated level with Australia and Kingman as the best three-year-old colt in the world. He has continued to compete in Group races until 2017 but did not recapture the form shown in his three-year-old season.

The Dante Stakes is a Group 2 flat horse race in Great Britain open to three-year-old horses. It is run over a distance of 1 mile, 2 furlongs and 56 yards at York in May.
