Elisabeth von Herzogenberg née Elisabeth von Stockhausen (born in Paris on 13 April 1847; died in Sanremo on 7 January 1892) was a German pianist, composer, singer and philanthropist.
Her father had served as a Hanoverian ambassador and was a pianist linked to Frédéric Chopin and Charles-Valentin Alkan. Although a Protestant, she married the Catholic Heinrich von Herzogenberg. She is known in large part for her association with Johannes Brahms, with whom she studied and with whom she and her husband corresponded copiously. As an aristocratic musician, she largely did not perform or publish for the public, but did arrange children's folk songs. Her lover, the composer Ethel Smyth, devoted chapter XX of Impressions That Remained: Memoirs to her.
