Andreas Armsdorff (also found as Andreas Armstroff in modern catalogues; 1670–1699) was a German organist and composer, born in Mühlberg (Drei Gleichen) and associated with Erfurt, where he died at the end of 1699. Authority records preserve his identity under multiple surname spellings and classify him as a composer-organist. His surviving footprint is centred on organ chorale preludes, with pieces such as Wie schön leuchtet der Morgenstern, Allein zu dir, Herr Jesu Christ, and Allein Gott in der Höh sei Ehr circulating under his name in modern access points and manuscript-copy cataloguing. Modern editions and recordings suggest a continuing specialist interest in this compact Thuringian repertory.
