Elizabeth Despencer, 3rd Baroness Burghersh (c. 1342 – August 1402) was an English noblewoman born to Bartholomew de Burghersh, 2nd Baron Burghersh and Cicely, de Weyland. Some recently constructed genealogies purport that she was first married, some time after 1347, to Maurice FitzGerald, 4th Earl of Kildare (d. 25 August 1390) and by him had at least four children. Yet it is more consistent with known dates of death of the 4th Earl of Kildare that he married instead Margaret, a daughter of the 1st Baron Burghersh. Otherwise there would be record of Kildare's divorce from Elizabeth and probably a mention in the original records of her 'remarriage' rather than of her 'marriage' to le Despencer.
