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 2,000 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. After her racing career ended in 1871, she became a broodmare for Graham until his death in 1876. Formosa was exported to France in 1879 and died there in February 1881. While she did not produce offspring that excelled at racing, her daughters that were exported to Germany and New Zealand did produce descendants that were successful racers.
