Elsa Beata Persdotter Brahe (1629 – 7 April 1653), Elizabeth Beatrice was a Swedish countess and duchess, married to Adolph John I, Count Palatine of Kleeburg, Duke of Stegeborg, the brother of king Charles X of Sweden.
She was the daughter of Per Brahe the Younger and Kristina Katarina Stenbock, and was raised by her paternal grandmother Elsa Gyllenstierna at Rydboholm Castle.
As the majority of female nobles at the time, her education mainly focused on how to manage an estate, and how to act in a representational social life.
Prior to her marriage, she served as maid of honour to queen Christina of Sweden.
