Royalty do not use last names in the traditional sense. When last names are necessary, such as in marriage, Prince William, Prince Harry, and the other descendants of Elizabeth II and Prince Philip are to use the name Mountbatten-Windsor. This means that Kate's last name is Mountbatten-Windsor, her full name is Catherine Elizabeth Mountbatten-Windsor, but she will be known by her title, the Duchess of Cambridge.
