Maria Augusta Nepomucena Antonia Francisca Xaveria Aloysia (German: Maria Augusta Nepomucena Antonia Franziska Xaveria Aloysia; Polish: Maria Augusta Nepomucena Antonia Franciszka Ksaweria Alojzia) of Saxony (21 June 1782 – 14 March 1863) was Princess of Saxony.

Between 1791 and 1795, she played a political role as the potential successor to the Polish throne.

Maria Augusta was a member of the House of Wettin as the daughter of Frederick Augustus I of Saxony and Amalie of Zweibrücken-Birkenfeld.

[2] Her father's hesitation in accepting this proposal and the subsequent Partitions of Poland in 1793-1795 prevented this from occurring.

One of her potential suitors was Prince Józef Poniatowski, the cousin of her earlier suggested spouse Stanisław.
