She was the third (but second surviving) daughter of Leopold I, Prince of Anhalt-Dessau, by his morganatic wife Anna Louise Föhse.
As the favorite child of her father, Anna Wilhelmine was given the Mosigkau Manor near Dessau for her residence in 1742. The princess, who remained unmarried all her life, began renovations on her new home with an architect from the Saxon school. From 1757 she spent her summers in the new Mosigkau Palace.
In the year of her death, Anna Wilhelmine ordered the establishment of a "Noble lady"s convent" (German: Hochadligen Fräuleinstiftes) in Mosigkau Castle.
The convent existed until 1945. Since then the Castle has been accessible as a museum.
