Dorothea Wilhelmine of Saxe-Zeitz (born: 20 March 1691 in Bad Elster ; died: 17 March 1743 in Kassel) was a duchess of Saxe-Zeitz by birth and by marriage Landgravine of Hesse-Kassel. Dorothea Wilhelmine was a daughter of the Duke Maurice William of Saxe-Zeitz (1664-1718) from his marriage to Maria Amalia (1670 - 1739), daughter of the Elector Frederick William I of Brandenburg. By 1710 all her siblings had died and so, after her father's death Dorothea Wilhelmine was the last surviving member of the house of Saxe-Zeitz.
