Ki Ming (1948–1957) was an Irish-bred British-trained Thoroughbred racehorse and sire best known for winning the classic 2000 Guineas in 1951. As a two-year-old he showed promise to win at Royal Ascot but his season was disrupted when his trainer was banned for a doping offence. At three, he recorded an upset win over a large field to win the Guineas but failed when favourite for the Epsom Derby. In autumn he returned to sprint distances and won the Diadem Stakes at Ascot.
