Princess Augusta Wilhelmina of Hesse-Darmstadt (German: Augusta Wilhelmina Maria von Hessen-Darmstadt; 14 April 1765 – 30 March 1796) was Duchess consort of Zweibrücken by marriage to Maximilian, Duke of Zweibrücken and the mother of King Ludwig I of Bavaria.

[1] There, Augusta Wilhelmina met Queen Marie Antoinette, with whom she maintained an ongoing correspondence.

In 1789, Maximilian's regiment rose in revolt and he and Augusta Wilhelmina fled to her parents' home in Darmstadt.

[3] In April 1795, Maximilian succeeded his brother as reigning Duke of Zweibrücken; however, his duchy was entirely occupied by the French.

In March 1796, Augusta Wilhelmina, who had always had delicate lungs, finally succumbed and died at Rohrbach [de].
