Queen Elizabeth II's surname is Windsor. However, it is worth noting that the British royal family's name has changed over the years. The Queen's full name at birth was Elizabeth Alexandra Mary Windsor. The name "Windsor" was adopted as the royal family's surname in 1917 during the reign of her grandfather, King George V, as a way to distance themselves from their Germanic-sounding name, House of Saxe-Coburg and Gotha, due to anti-German sentiment during World War I. In 1960, Queen Elizabeth II issued a declaration stating that her direct descendants, other than those with the style of Royal Highness and the title of Prince/Princess, would bear the surname Mountbatten-Windsor, combining the surnames of her husband, Prince Philip, Duke of Edinburgh (whose surname was Mountbatten), and her own family name, Windsor.
