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 Wales
After 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.
On 9 April 1952, Queen Elizabeth II officially declared her
"Will and Pleasure that I and My children shall be styled and known as the House and Family of Windsor, and that my descendants who marry and their descendants, shall bear the name of Windsor."
On 8 February 1960, the Queen confirmed that she and her children would continue to be known as the House and Family of Windsor, as would any agnatic descendants who enjoy the style of Royal Highness, and the title of Prince or Princess.
(agnatic succession is the limitation of inheritance to a throne)
Elizabeth II also decreed that her agnatic descendants who do not have that style and title would bear the surname Mountbatten-Windsor.
Kate Middleton's last name will therefore be 'Windsor".
Kate Middleton will be known as the Duchess of Cambridge or Princess Catherine.
Catherine Middleton will be known as Her Royal Highness the Duchess of Cambridge.
