Attila (1839–1846) was a British Thoroughbred racehorse and sire. In a career that lasted from August 1841 to June 1844 he ran thirteen times and won eight races. He began his career with a run of six successive wins, culminating in the 1843 Derby. His later form was disappointing and he never won another competitive race: his two subsequent "victories" were the result of walkovers in races in which he was unopposed. He had little chance to prove himself as a stallion as he died at the age of seven from injuries sustained in an accident on board a ship in the English Channel.

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.
