Horse racing in Ireland is intricately linked with Irish culture and society. The racing of horses has a long history on the island, being mentioned in some of the earliest texts. Domestically, racing is one of Ireland's most popular spectator sports, while on the international scene, Ireland is one of the strongest producers and trainers of Thoroughbred horses. The Irish horse racing industry is closely linked with that of Great Britain, with Irish horses regularly competing and winning on the British racing circuit.
