Luise Marie of the Palatinate

Luise Marie of the Palatinate (Luise Marie von der Plafz; 23 July 1647 – 11 March 1679) was a Bavarian princess who married Charles Theodore, the Prince (Fürst) of Salm-Salm. A great-granddaughter of James I of England and niece of Sophia, Electress of Hanover, she and her family, as Catholics, were excluded from the line of succession to the British throne.

She was the eldest daughter of the landless Prince Palatine Edward and his French-Italian wife, Anna Gonzaga. She was probably named after her mother's sister, Ludwika Maria Gonzaga, Queen of Poland (in German, Louise Marie). Her younger sisters were Anne Henriette, wife of Henri Jules, Prince de Condé and Benedicta Henrietta, wife of John Frederick, Duke of Brunswick-Lüneburg. On her father's side, she was a first cousin of George I of Great Britain and Elisabeth Charlotte, Duchess of Orléans.

On March 20, 1671, she married Charles Theodore, Prince of Salm. They had four children, a son named Louis Otto who became the last Prince of Salm-Salm, and three daughters, Louise, Louise Apollonia, and Eleanor Christina, two of whom died without issue.
