The Duke of York Stakes is a prestigious flat horse race held annually in May at the York Racecourse in England. It is a Group 2 race, which means it features some of the best thoroughbred horses competing over a distance of six furlongs. The event is open to horses aged three years and older, attracting top trainers and jockeys. Established in 1968, the race is named after the title held by the Duke of York, a member of the British royal family. The Duke of York Stakes is part of the British flat racing season and often serves as a key preparation race for other major events, including the Royal Ascot.
