Whisk Broom II (1907–1928) was an American-bred Thoroughbred racehorse who raced in the United Kingdom (under the name Whisk Broom) and in the United States. Whisk Broom showed high class form during four seasons of racing in Europe, but produced his best performances when returning to America in 1913. He claimed the New York Handicap Triple by winning the Metropolitan Handicap, the Brooklyn Handicap, and the Suburban Handicap, a feat unmatched until Tom Fool achieved it forty years later. Kelso in 1961 and Fit To Fight in 1984 later joined them as the only other horses to win the Handicap Triple. Whisk Broom II's career was ended by injury after his triple success, but he went on to become a successful breeding stallion.
