Maria Euphrosyne de la Gardie was a princess and palatine countess, daughter of Johan Casimir of Zweibrücken and Princess Katarina of Sweden. In 1647 she married Lord High Chancellor, Count Magnus Gabriel de la Gardie.
Her autobiography of 1682, written into a prayer book, follows the aristocratic tradition of biographies and is printed in Handlingar til upplysning af svenska historien, Uppsala 1789, published by E. M. Fant. The manuscript is kept in the De la Gardie archive at Lund University Library.
