Galliard was a British Thoroughbred racehorse and sire. He showed top-class form as a two-year-old in 1882 when he won the Chesterfield Stakes at Newmarket and the Prince of Wales's Stakes at York. In the following year he won the 2000 Guineas and then ran third when favourite for the Epsom Derby. His performances in these two races led to some questions regarding the integrity of his regular jockey Fred Archer. At Ascot Racecourse he recorded a hat-trick of wins when he took the Prince of Wales's Stakes, St James's Palace Stakes and Triennial Stakes. He was strongly fancied for the St Leger but his racing career was ended by injury. He had some influence as a breeding stallion through his son War Dance and his daughter Black Duchess.

The 2000 Guineas Stakes is a Group 1 flat race in Great Britain open to three-year-old thoroughbred colts and fillies. It is run on the Rowley Mile at Newmarket over a distance of 1 mile (1.6 km) and scheduled to take place each year at the start of May.
