The Irish Greyhound Derby held at Shelbourne Park, is the premier greyhound racing competition in Ireland. First held at Harold's Cross in 1928, the event was unofficial until 1932 and called the National Derby. The first winner in 1928 was Tipperary Hills who won in a time of 30.56 sec at a starting price of 1-1f. It controversially switched to Shelbourne Park in 1932 and then it was held in alternate years between the two tracks. Today it is considered to be one of the two biggest races in the calendar by the UK & Ireland greyhound racing industries, alongside the English Greyhound Derby.
