Countess Maria Wilhelmina von Neipperg (later Princess of Auersperg) (30 April 1738 - 21 October 1775) was an Austrian noble and court official, known as the mistress of Francis I, Holy Roman Emperor. By birth, she was member of an ancient House of Neipperg and by marriage member of the House of Auersperg.
In April 1756, she married Prince Johann Adam Joseph von Auersperg (1721-1795), upon the wish of the Empress Maria Theresa. She remained in a liaison with the Emperor until his death in 1765,[4] however she never had any position of being an official mistress, and their relationship, though known, was never confirmed.[5] Wilhelmina also had an affair with Charles-Joseph Lamoral.[6] She had no children.
