Misty Morn (1952–1971) was an American Thoroughbred racehorse.
Bred and owned by Gladys Mills Phipps' Wheatley Stable, at age three Misty Morn broke the Jamaica Racetrack track record en route to winning the 1955 Gallant Fox Handicap.
The filly ended up the year as the American Champion Three-Year-Old Filly and American Champion Older Female Horse after additional wins in the Molly Pitcher, Monmouth Oaks and Diana Handicap.
Retired to breeding at Claiborne Farm in Paris, Kentucky, Misty Morn was the 1963 Broodmare of the Year.
Two of her foals earned American Champion Two-Year-Old Colt honors: Bold Lad in 1964 and Successor in 1966.
