Irish Derby

The Irish Derby (Irish: Dearbaí na hÉireann) is a Group 1 flat horse race in Ireland open to three-year-old thoroughbred colts and fillies. It is run at the Curragh over a distance of 1 mile and 4 furlongs (2,414 metres), and it is scheduled to take place each year in late June or early July.

It is Ireland's equivalent of the Derby Stakes, and it is usually held four weeks after the English race.

The earliest version of the Irish Derby was an event called the O'Darby Stakes. This was established in 1817, but it was discontinued after 1824. A subsequent race titled the Curragh Derby was inaugurated in 1848, but this was again short-lived.^{[citation needed]}

The modern Irish Derby was created by the 3rd Earl of Howth, the 3rd Marquess of Drogheda and the 3rd Earl of Charlemont. It was first run in 1866, and it was initially contested over 1 mile, 6 furlongs and 3 yards. It was extended by 9 yards in 1869, and cut to its present distance in 1872. The first Epsom Derby winner to achieve victory in the Irish version was Orby, trained in Ireland by Fred McCabe, in 1907.^{[citation needed]}

The Irish Derby became a major international race in 1962, when its prize money was substantially increased. Joe McGrath, a founder of the Irish Hospitals' Sweepstake, combined the race with the sweepstake, and it became known as the Irish Sweeps Derby. The event began to regularly attract the winners of the Epsom Derby, and Santa Claus became the second horse to win both races in 1964.^{[citation needed]}

The Irish Derby was sponsored by Budweiser from 1986 to 2007, and it has been backed by Dubai Duty Free since 2008. It is currently staged on the third day of the Curragh's three-day Irish Derby Festival meeting.^{[citation needed]}

Twenty horses have now completed the English-Irish Derby double, and the most recent was Lambourn in 2025.
