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.
