Princess Elizabeth of Clarence (Elizabeth Georgiana Adelaide; 10 December 1820 – 4 March 1821) was a member of the British royal family. She was the second daughter of the Duke and Duchess of Clarence and St Andrews, later King William IV and Queen Adelaide. Princess Elizabeth was a granddaughter of King George III.
The generations indicate descent from George I, who formalised the use of the titles prince and princess for members of the British royal family. Where a princess may have been or is descended from George I more than once, her most senior descent, by which she bore or bears her title, is used.
