Lethal Force (foaled 10 April 2009) is an Irish-bred, British-trained Thoroughbred racehorse. As a two-year-old in 2011 he showed potential but failed to win in four races. In the following year he recorded his first major success when winning the Hungerford Stakes. In 2013, Lethal Force emerged as one of the leading sprinters in the world by defeating strong international fields in both the Diamond Jubilee Stakes and the July Cup.
