Catherine of Pfalz-Zweibrücken (10 December 1661 – 27 May 1720), was the daughter of Adolph John I, Count Palatine of Kleeburg and Countess Elsa Elisabeth Brahe of Wisingsborg, cousin of Charles XI of Sweden and the sister of Adolph John II, Count Palatine of Kleeburg and Gustav, Duke of Zweibrücken. She is foremost known for the scandal involving herself and her siblings, when she, after a long ongoing conflict in 1686-88, escaped from the authority of her parents.
