Fanny Edle von Geiger-Weishaupt was a German landscape painter.

Fanny Edle von Geiger-Weishaupt grew up in Edenbergen near Augsburg, where her father was a forester. In 1890 she moved to Etzenhausen near Dachau and married the animal and landscape painter Viktor Weishaupt (1848-1905), a professor at the State Academy of Fine Arts in Karlsruhe, who was fourteen years her senior. She received her artistic training at the Royal School of Applied Arts in Munich and under Ludwig von Herterich (1856–1932) at the Damenakademie (Ladies' Academy) of the Munich Association of Women Artists. During this time, she undertook study trips to France, Greece, the Netherlands and Switzerland. After the death of her husband, she moved to Munich in 1905, where she died in 1931.
