Brief Truce (foaled 8 May 1989) was an American-bred, Irish-trained Thoroughbred racehorse and sire. After winning his only race as a juvenile in 1991 he improved in the spring of the following year to finish third in the Irish 2000 Guineas and win both the Amethyst Stakes and the Gallinule Stakes. In June he recorded his biggest win when he defeated a very strong field in the St James's Palace Stakes at Royal Ascot. Later that year he was placed in the Prix du Moulin, Queen Elizabeth II Stakes and Breeders' Cup Mile. After his retirement from racing he had some success as a breeding stallion in Australia.
