Fiddle Dancer Boy (1978–1991) was a Canadian Thoroughbred racehorse who won the 1981 Queen's Plate, Canada's most prestigious race and North America's oldest annually run stakes race. Bred by prominent Ontario owner/breeder , he was sired by Nice Dancer, the 1972 Canadian Champion Three-Year-Old Male Horse. He was out of the mare Fiddly Dee, whose sire was 1961 Canadian Horse of the Year Hidden Treasure. As a yearling, Fiddle Dancer Boy was purchased for $20,000 by Toronto car dealer Jack Carmichael and his brother Donald on the recommendation of future Hall of Fame trainer Jim Bentley.
