The Grand National is a greyhound racing competition held annually at Curraheen Park in Cork, Ireland. The race was inaugurated in 1928 at Shelbourne Park and was shared between the two Dublin tracks of Shelbourne and Harold's Cross Stadium before being switched to the old Cork (Western Road) Greyhound Stadium just before World War II. It is the leading hurdle event in Ireland and is an integral part of the Irish greyhound racing calendar.
