Bold Personality was an Australian Thoroughbred racehorse who gained notability by being substituted for the inferior horse Fine Cotton in a race at Eagle Farm Racecourse, Brisbane on 18 August 1984. The attempted scam is infamous in Australian history due to the involvement of some of racing's elite. Bold Personality, poorly disguised as Fine Cotton, won the race by a small margin after being backed from 33/1 into odds of 7/2, but Racing Stewards were suspicious and rumours of a ring-in quickly spread around the racecourse.
