Happy Laughter (foaled 1950) was a British Thoroughbred racehorse and broodmare best known for winning the classic 1000 Guineas in 1953. As a two-year-old, Happy Laughter won five races but was badly affected by sinus problems which were only rectified by surgery in the winter of 1952/1953. As a three-year-old she followed up her win in the Guineas by taking the Coronation Stakes, Falmouth Stakes and Nassau Stakes before being retired to stud.
