Countess Franciszka Krasińska (9 March 1742 in Maleszowa – 30 April 1796 in Dresden), was a Polish noblewoman and wife of Charles of Saxony, Duke of Courland, the son of King Augustus III of Poland.

The Krasińskis attended the royal court in Warsaw, where she would eventually meet her future husband, Charles of Saxony, Duke of Courland.

Her paternal aunt, Princess Zofia Lubomirska, on the other hand, took a sober attitude and commented that her brother and husband "... are convinced that his daughter will one day rule...

After the death of Franciszka's compliant father in 1762, aunt Zofia's husband, Prince Antoni Lubomirski, became legal guardian of her "officially unmarried" niece and her three sisters.

In January 1764, during the Interregnum, Charles did officially recognize the marriage, and Zofia Lubomirska tried to negotiate with him to have him announce his candidacy for the Polish throne, which would have given Franciszka the chance to become queen.
