Pretty Polly (March 1901 – 17 August 1931) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. One of the greatest fillies ever to race in Britain, she won fifteen consecutive races and was only the fifth horse to win the British Fillies Triple Crown since its inception in 1814. Pretty Polly also became one of the greatest broodmares of the century.
Breeding
Her sire was the good stallion, Gallinule who was also a roarer and bleeder. Pretty Polly's dam was the cluster mare, Admiration by Saraband, who won two small races in Ireland, before being tried as a steeplechaser. and founded a successful female family, which included top class gallopers Craganour, Cresta Run, King John and Tehran.

Pretty Polly was bred and owned by Major Eustace Loder and trained by Peter Gilpin, she won nine races from nine starts as a two-year-old in 1903.
The following year, Pretty Polly won the 1,000 Guineas as 1-4 favourite, winning easily by three lengths in record time. Other wins as a three-year-old were The Oaks, the Coronation Stakes at Royal Ascot, the Nassau Stakes at Goodwood, the St. Leger Stakes (completing the Fillies' Triple Crown) and the Park Hill Stakes with jockey William Lane.
Pretty Polly stayed in training as a four and five-year-old, winning six more races, including the Coronation Cup in 1905 and 1906.
In total, Pretty Polly won 22 of her 24 races, placing second twice, in Paris in 1904 and in the 1906 Ascot Gold Cup.
