L'Abbesse de Jouarre (1886 – 6 March 1897) was a Thoroughbred racehorse that won the 1889 Epsom Oaks. The horse was owned by Lord Randolph Churchill and the Earl of Dunraven during her three-year racing career. She was nicknamed "Abscess on the Jaw" during her career due to the difficulty the public had pronouncing her name. A versatile racehorse, L'Abbesse was able to win major races at distances ranging from six furlongs to one-and-a-half miles. Retired from racing in 1891, she was the dam of the influential German broodmare Festa and the leading stallion Desmond. L'Abbesse de Jouarre died on 6 March 1897 during foaling.
