Princess Maria Anna of Bavaria (German: Maria Anna Leopoldine Elisabeth Wilhelmine von Bayern; 27 January 1805 – 13 September 1877), known as 'Marie' was Queen of Saxony from 1836 to 1854 as the second wife of King Frederick Augustus II of Saxony.

Maria Anna was born in Munich, the daughter of Maximilian I Joseph of Bavaria and his second wife, Karoline of Baden.

In 1836, Frederick succeeded his uncle Anthony as king, making her queen.

In 1836, during the great famine of Erzgebirge and Vogtland in Saxony, Maria Anna organized the first women committees to help, "Frauenvereinsanstalt der obererzgebirgischen und vogtländischen Frauenvereine" — this was in 1859 renamed "Zentralausschuß der obererzgebirgischen und vogtländischen Frauenvereine" and existed until 1932.
