Bally Ache (February 3, 1957 – October 28, 1960) was an American Thoroughbred racehorse who won the Preakness Stakes in 1960 but died later only five months later from an intestinal ailment.
In her book American Classic Pedigrees (1914–2002), author Avalyn Hunter wrote that Bally Ache was "a crowd favorite" who "won hearts by his sheer determination."
Bally Ache was a bay horse bred by brothers Alan and Marvin Gaines at their Twin Oak Farm in Walton, Kentucky.
Despite Bally Ache's second-place finish, it did not deter the Turfland racing syndicate led by Joseph L. Arnold, who bought the colt for what Sports Illustrated magazine described as the "staggering price of $1,250,000".
Entered in the Belmont Stakes, the third leg of the Triple Crown, Bally Ache came up lame the day before the race and was withdrawn.
