Baroness Franziska "Fanny" von Arnstein (29 September 1758 – 8 June 1818), born Vögele Itzig, was a Viennese socialite and salonnière and a supporter of both Mozart and Beethoven.

Fanny Arnstein was born in Berlin, the daughter of Daniel Itzig. She was a member of the extensive and influential Jewish Itzig family.

She married the banker Nathan Adam von Arnstein, a partner in the firm of Arnstein and Eskeles; her sister Cäcilie von Eskeles was married to the other partner, Bernhard von Eskeles. They brought the social influences of Berlin, notably the concept of the intellectual salon, to the Vienna of Joseph II. The Arnstein mansion at Vienna and her villas at Schönbrunn and Baden bei Wien were regularly used for hospitality. She was also involved in charitable works.

During the Vienna Congress the Arnstein salon was frequented by celebrities including Beethoven, Wellington, Talleyrand, Hardenberg, Rahel Varnhagen and her husband, the Schlegels, Justinus Kerner, Karoline Pichler, and Zacharias Werner. She was one of the founders of the Gesellschaft der Musikfreunde and was herself a skilled musician.

In 1814, Fanny von Arnstein introduced a new custom from Berlin, hitherto unknown in Vienna: the Christmas tree.^[1]

Her only daughter, Henrietta, Baroness Pereira-Arnstein, was also a skilled musician and a regular correspondent of her cousin, Lea Salomon, wife of Abraham Mendelssohn and mother of Felix and Fanny Mendelssohn (who was named after Fanny Arnstein).
