The Princess Margaret Stakes is a Group 3 flat horse race in Great Britain open to two-year-old fillies.
It is run at Ascot over a distance of 6 furlongs (1,207 metres), and it is scheduled to take place each year in July.
The event is named after Princess Margaret, the younger daughter of King George VI.
It was established in 1946, and the inaugural running was won by Orum Blaze.
For a period it was classed at Listed level, and it was promoted to Group 3 status in 1986.
