The King Edward VII Stakes is a Group 2 flat race over 1 mile 3 furlongs and 211 yards, open to three-year-old colts and geldings, and takes place on the fourth day of the Royal meeting. It was originally known as the Ascot Derby, and in the early days both Oaks and Derby winners contested the race, but it was changed to its present name in 1926 in memory of King Edward VII.
Early history:- The inaugural running of the Ascot Derby, forerunner of the King Edward VII Stakes, was held on Tuesday 17th June 1834 when won by the Epsom Oaks winner Pussy (4/7 fav), who beat Oaks runner-up Louisa by a length with two Derby subscribers behind, although those two colts did not ultimately contest the Epsom Derby.

The King Edward VII Stakes, took place at York on Friday 17th June 2005 over the mile and a half course starting at the Swinley Post, and was won by a bay colt by Machiavellian out of Time Saved, winning a first prize of £75,400 (equivalent to £115,000 in 2020).
