Canterbury Pilgrim (1893–1917) was a British Thoroughbred racehorse and broodmare. She showed some ability as a juvenile but failed to win a race. She won the Oaks Stakes on her first run as a three-year-old and went on to win the Liverpool Summer Cup, Park Hill Stakes and Jockey Club Cup before being retired at the end of the year. As a broodmare the best of her offspring was Swynford, a top-class racehorse who was even better as a breeding stallion. She also produced the influential sire Chaucer and several good broodmares. She has been described as "one of the most influential horses, stallion or mare, of the Twentieth Century".

The Oaks Stakes is a Group 1 flat horse race in Great Britain open to three-year-old fillies. It is run at Epsom Downs over a distance of 1 mile, 4 furlongs and 6 yards, about 1½ miles, and it is scheduled to take place each year in late May or early June. It is the second-oldest of the five Classic races, after the St Leger. Officially the Betfred Oaks, it is also popularly known as simply The Oaks. It has increasingly come to be referred to as the Epsom Oaks in both the UK and overseas countries, although 'Epsom' is not part of the official title of the race.)
