Formosa (1865–1881) was a British Thoroughbred racehorse that was the first winner of the English Fillies Triple Crown in addition to running a dead heat with the colt Moslem for the 2000 Guineas Stakes. Formosa was bred by James Cookson and was foaled in 1865 at his Neasham Hall stud farm. Formosa was sold to William Graham (who raced under the pseudonym G. Jones) in 1866 and raced her entire three-year racing career under his ownership.
