Adelheid Maria Eichner (1762–1787) was a German composer, singer and pianist who was noted during her brief lifetime for her fine three-octave singing voice and vocal technique.
He had travelled to Paris and London to give concerts and had begun his employment in the Hofkapelle of the Prince Frederick William in August 1773.
Adelheid Eichner first came to prominence as a composer in 1780, when her 12 Lieder mit Melodien fürs Clavier was published in Potsdam.
Eichner set poems by G. A. Bürger and J. D. Overbeck, as well as those of the Dutch General von Stamford, who from about 1775 until 1786 was a tutor at the Prince of Prussia's court and according to Zelter, was engaged to her.
