The Prix de Sandringham is a Group 2 flat horse race in France open to three-year-old thoroughbred fillies.
It is run at Chantilly over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in late May or early June.
The event was originally called the Prix des Lilas, and it used to be held at Longchamp.
During the early part of its history it was contested over 2,000 metres, and it served as a trial for the Prix de Diane.
The race was titled the Coupe de Sa Majesté la Reine Elizabeth in 1972, in honour of Queen Elizabeth II, who was attending Longchamp during a state visit to France.
