Gisela von Arnim (also Giesela; August 30, 1827 in Berlin – April 4, 1889 in Florence) was a German writer, mainly of fairy tales.

With her sisters she started the "Kaffeter circle",[5] first a group for young women and later a full literary salon also including men (honorary members included Hans Christian Andersen and Emmanuel Geibel).

[6] A painful relationship developed[7][8] and only ended after Gisela von Arnim married Herman Grimm in 1859.

[6] In 1853 she met Johannes Brahms and Joachim through their mutual acquaintances Robert and Clara Schumann.

[11] Gisela von Arnim's letters to Joseph Joachim are unpublished, and are at the Freies Deutsches Hochstift, Frankfurt.
