Marling (foaled 17 March 1989) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. She was one of the leading European two-year-olds of 1991 when she was unbeaten in four races including the Queen Mary Stakes and Cheveley Park Stakes. In the following year she was narrowly beaten in the 1000 Guineas but went on to win the Irish 1000 Guineas, Coronation Stakes and Sussex Stakes. She was retired to stud at the end of 1992 and has had some success as a dam of winners.
