Henriette von Pereira-Arnstein (29 November 1780 – 13 May 1859) was an Austrian pianist and salon-holder.

[1][2] Henriette was educated at her parents' home, and she studied the piano with Muzio Clementi and Johann Andreas Streicher.

She married in 1802 the banker Heinrich Freiherr von Pereira (1773–1835); they had three sons and a daughter.

She had a strong friendship with Theodor Körner, and his song cycle Leier und Schwert ("Lyre and Sword") was written for her.

[1][2][3] Like her mother, she was involved in many charities; she was director of the Marienspital in Baden bei Wien.
