Bona Vista (1889–1909) was a British Thoroughbred racehorse. As a two-year-old he won the Woodcote Stakes at Epsom Downs. As a three-year-old he won the Newmarket Biennial Stakes, before winning the 2000 Guineas Stakes by one and a half lengths. He was trained by William Jarvis and owned by Charles Day Rose. After retiring from racing Bona Vista became a successful stallion, siring Ascot Gold Cup winner Cyllene. Through his son Cyllene and grandson Polymelus, Bona Vista's sire line is the most dominant in Thoroughbred racehorses today.

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.
