The Ellen Chaloner Stakes is a Listed flat horse race in Great Britain open to fillies and mares aged three years or older.
It is run at Newmarket over a distance of 6 furlongs (1,207 metres), and it is scheduled to take place each year in May.
The race was first run in 2000 at Nottingham and originally titled the Kilvington Fillies' Stakes.
It was moved to Newmarket in 2022 and given its present title in 2023 in honour of Ellen Chaloner (d.1944).
In 1886 Chaloner became the first woman to be licensed to train racehorses in Great Britain.
