Who Is Harry Diamond?
Harry Diamond is a professional golf caddie and former amateur golfer from Northern Ireland, best known for his long-standing partnership and friendship with Rory McIlroy, one of the world’s top golfers. Born in Belfast, Northern Ireland, Diamond has played a crucial role in McIlroy’s career, serving not only as his caddie but also as one of his most trusted confidants. His deep understanding of the game, calm demeanour, and strategic insight have helped McIlroy remain competitive at the highest levels of international golf.
Before becoming a professional caddie, Harry Diamond was an accomplished amateur golfer himself. He played competitively in Ireland and was highly regarded for his sharp short game and consistent performances. He notably won the West of Ireland Championship and the North of Ireland Championship, two of the most prestigious events in Irish amateur golf.
Diamond and McIlroy’s friendship goes back to their childhood — they have known each other since they were teenagers and even represented the same golf clubs in Northern Ireland. In 2017, McIlroy appointed Diamond as his full-time caddie after parting ways with his previous caddie, J.P. Fitzgerald. Since then, the duo has enjoyed several victories on the PGA Tour and European Tour, including major wins and top finishes in global tournaments.
Beyond golf, Harry Diamond leads a private life, preferring to stay out of the media spotlight despite his proximity to one of golf’s biggest stars.
