Dorothea "Dolly" de Ficquelmont (14 October 1804, Saint Petersburg, Russian Empire – 10 April 1863, Venice, Austrian Empire), born Countess Dorothea von Tiesenhausen (Daria Fyodorovna in Russian), was a Russian writer and salonist. A granddaughter of the Russian war hero General Prince Kutuzov (who distinguished himself in the Napoleonic Wars), she was a Russian of German Baltic origin, and later a member of the Austrian nobility as the wife of Count Karl Ludwig von Ficquelmont.
Dolly von Tiesenhausen was the daughter of Count Ferdinand von Tiesenhausen, aide-de-camp of Emperor Alexandre I of Russia who died at Austerlitz, and of Princess Elisabeth "Lisa" (sometimes "Elisa") Koutouzova, daughter of Prince Kutuzov. Her mother remarried in 1811 to Count Nicolas Khitrovo, Russian special envoy to the Grand Duchy of Tuscany. From 1815, Dolly von Tiesenhausen spent her childhood with her mother and her sister Catherine — future lady-in-waiting of the Imperial Court of Russia — in Reval, then moved to Florence where she spent the rest of her youth.
On 3 June 1821 she married Count Charles-Louis de Ficquelmont, Austrian Ambassador before the Habsbourgs-Tuscany, who was 27 years her senior. Following their marriage, the Count was appointed Ambassador to the Court of King Ferdinand I of Two Sicilies in Naples. In spite of the revolutionary troubles in the Kingdom of Two Sicilies and the increasing tensions between Austria and Naples, the Ficquelmonts perfectly integrated into Naples' aristocratic high society.
