Elizabeth of the Palatinate (16 November 1483 in Heidelberg – 24 June 1522 in Baden-Baden) was a member of the House of Wittelsbach and a Countess Palatine of Simmern and by marriage, successively Landgravine of Hesse-Marburg and Margravine of Baden.
The marriage tied William III closer to the Palatinate house while his cousins in Kassel were considered to be partisans of the Emperor.
In the event he would die without an heir, William had promised Elizabeth almost the entire county of Katzenelnbogen as wittum.
[1] Three years after the death of her first husband Elisabeth married on January 3, 1503, in Heidelberg with Margrave Philip I of Baden-Sponheim (1479–1533).
[2] Elizabeth died on June 14, 1522, and was buried in the Collegiate Church in Baden-Baden.
