The Bug (1943–1963) was an Irish-bred Thoroughbred racehorse and sire. A specialist sprinter, he was trained first in Ireland and then in Britain during a racing career which lasted from 1945 until September 1947. After being beaten in his first three races he recorded ten consecutive victories including the Wokingham Stakes, July Cup, Nunthorpe Stakes, Diadem Stakes and Cork and Orrery Stakes.
