Winston Walter Frederick Percy is a British former motor racing driver from England. Percy was British Touring Car Champion three times, and at the time of his retirement was the most successful non-Antipodean driver ever to compete in Australia's premier national motorsport event, the Bathurst 1000km. Joe Saward of Autosport magazine said he was "often regarded as the World's Number One Touring Car Driver".
