Myrobella (foaled 1930) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. Bred by the British National Stud she was the outstanding two-year-old of either sex in Britain in 1932 when she won five consecutive races. In the following year she failed to stay the distance in the 1000 Guineas but had considerable success when reverting to sprint distances, winning the July Cup, King George Stakes and Challenge Stakes. On her retirement from racing she became a successful and influential broodmare.
