Titles Given by Queen Elizabeth:Shortly before their wedding, Queen Elizabeth released the titles William and Kate will be known by. Kate's first title will be Duchess of Cambridge, her second title is Countess of Strathearn, and her third title is Baroness Carrickfergus.Previous answer: Her Royal Highness Princess William of WalesAfter her marriage to Prince William of Wales, Kate Middleton's title will be Her Royal Highness Princess William of Wales. On the engagement announcement, Kate used her full name, Catherine. So she will likely be known as Princess Catherine of Wales.If Prince William receives a dukedom following the marriage, she will be known as Duchess in addition to Her Royal Highness.Kate Middleton will not be "Princess Catherine." Unless Prince William granted a peerage on marriage, she will be Princess William - just as the present Duchess of Gloucester was "Princess Richard" before the death of her father-in-law and the wife of Prince Michael of Kent is "Princess Michael." So she will be Her Royal Highness Princess William of Wales.Diana Princess of Wales was never "Princess Diana," no matter what the press called her. At the time of her marriage, she became HRH The Princess of Wales; after her divorce, she was Diana, Princess of Wales. The title "Princess" with a woman's given name is reserved for those who are so titled from birth - the daughters of the Sovereign or of a Prince.
