The Derby Day is a large oil painting showing a panoramic view of The Derby, painted by the English artist William Powell Frith over 15 months from 1856 to 1858. It has been described by Christie's as Frith's "undisputed masterpiece" and also "arguably the definitive example of Victorian modern-life genre."

The Derby Stakes, also known as the Derby or the Epsom Derby, is a Group 1 flat horse race in England open to three-year-old colts and fillies. It is run at Epsom Downs Racecourse in Surrey on the first Saturday of June each year, over a distance of one mile, four furlongs and 10 yards, or about 1½ miles. It was first run in 1780.
