The Pretty Polly Stakes is a Listed flat horse race in Great Britain open to three-year-old fillies.
It is run over a distance of 1 mile and 2 furlongs (2,012 metres) on the Rowley Mile at Newmarket in late April or early May.
The event is named after Pretty Polly, the winner of the fillies' Triple Crown in 1904.
It was established in 1962, and was originally staged at Newmarket's mid-May fixture.
