Queen's Hussar (1960–1981) was a British Thoroughbred racehorse and sire. He won the Washington Singer Stakes as a two-year-old in 1962 before taking the Lockinge Stakes and the top-class Sussex Stakes in 1963. He was retired to stud where his record was initially disappointing. However, he went on to sire the classic winners Brigadier Gerard, the highest-rated British horse of the twentieth century, and Highclere.
