Rahel Antonie Friederike Varnhagen () (née Levin, later Robert; 19 May 1771 – 7 March 1833) was a German writer who hosted one of the most prominent salons in Europe during the late 18th and early 19th centuries. She is the subject of a celebrated biography, Rahel Varnhagen: The Life of a Jewess (1957), written by Hannah Arendt. Arendt cherished Varnhagen as her "closest friend, though she ha[d] been dead for some hundred years". The asteroid 100029 Varnhagen is named in her honour. Life and works Rahel Antonie Friederike Levin was born to a Jewish family in Berlin. Her father, a wealthy jeweller, was a strong-willed man who ruled his family despotically. She became close friends with Dorothea and Henriette, daughters of the philosopher Moses Mendelssohn. Through them she got to know Henriette Herz, with whom she would become intimately associated throughout her life, moving in the same intellectual spheres. Together with Herz and her cousin, Sara Grotthuis née Meyer, she hosted one of the famous Berlin salons of the 1800s.

This period was one of misfortune for Germany; Prussia was reduced to a small kingdom and its king was in exile. Secret societies were formed in every part of the country with the object of throwing off the tyranny of Napoleon. Levin herself belonged to one of these societies. In 1814, she married the biographer Karl August Varnhagen von Ense in Berlin, after having converted to Christianity — this also made her sister-in-law to the poet Rosa Maria Assing. At the time of their marriage, her husband, who had fought in the Austrian army against the French, belonged to the Prussian diplomatic corps, and their house in Vienna became a meeting place for Prussian delegates to the Congress of Vienna. In 1815, she accompanied her husband to Vienna and then to Karlsruhe in 1816, where he became a Prussian representative. She returned to Berlin in 1819, when her husband retired from his diplomatic position. Though never the author of a
