The Champion Stakes is a Group 1 flat horse race in Great Britain open to thoroughbreds aged three years or older. It is run at Ascot over a distance of 1 mile 1 furlong and 212 yards (2,004 metres), and it is scheduled to take place as part of British Champions Day each year in October.
The event was established in 1877, and it was originally held at Newmarket. The inaugural running was won by Springfield. By the end of the century it had been won by five Classic winners.
The present system of race grading was introduced in 1971, and the Champion Stakes was classed at the highest level, Group 1.
The race was included in the Breeders' Cup Challenge series in 2009 and 2010. The winner earned an automatic invitation to compete in the Breeders' Cup Turf.
The Champion Stakes was transferred to Ascot in 2011. It became part of a newly created fixture called British Champions Day. It now serves as the middle-distance final of the British Champions Series.
With an increased prize fund of ã1,300,000, the Champion Stakes was Britain's richest horse race in 2011. The status was reclaimed by The Derby in 2012.
