German literary hostess from early in the 19th century whose soirees were attended by many of the German Romantics, notably August Wilhelm von Schlegel (Schlegel, August Wilhelm von), Friedrich von Schlegel (Schlegel, Friedrich von), Ludwig Tieck (Tieck, Ludwig), and Heinrich Heine (Heine, Heinrich).

Levin was from a wealthy Jewish family of Berlin. Her brother Ludwig Robert was a minor playwright. Literary salons presided over by such women as Levin and Henriette Herz became the centres of social activity for writers and their followers in Berlin. A sudden loss of fortune in 1806 interrupted Levin's salon activity, but she was able to resume it after she met Karl August Varnhagen von Ense (Varnhagen von Ense, Karl August), a writer and literary personality, in 1808. They were married in 1814. In 1819 he was dismissed from the diplomatic service because of his liberal politics, and the family returned to Berlin, where her salon regained its prominence. After her death, her husband published a collection of her writings as Rahel: ein Buch des Andenkens für ihre Freunde, 3 vol. (1834; “Rahel: A Book of Memories for Her Friends”). Briefwechsel, a four-volume edition of her letters, appeared in 1966–68.
