William Clift (1762–1840), born Wentworth, South Yorkshire, was a British jockey. He won the first runnings of both the 1,000 Guineas and 2,000 Guineas and was the first jockey to win all five of the British Classics.

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.
