Elisabet Charlotta Piper (26 April 1787 - 26 February 1860), was a Swedish court official.
She served as överhovmästarinna (Senior lady-in-waiting) to the crown princess of Sweden, Josephine of Leuchtenberg, from 1823 to 1835.
She was the daughter of Count Eric Ruuth and Elisabet Charlotta Wahrendorff, and married her sisters brother-in-law, the courtier count Erik Piper (1773-1833) in 1805, with whom she had two children.
She was appointed senior lady-in-waiting upon the arrival of the new crown princess in 1823.
She was persuaded to accept the post after it had been declined by Aurora Wilhelmina Brahe: Jacob De la Gardie described her: Queen Désirée compared her favorably to her own senior lady-in-waiting Vilhelmina Gyldenstolpe in a letter to her sister Julie Clary in March 1831: She was succeeded by Charlotta Skjöldebrand in 1836.
