Jakob Friedrich Kleinknecht (8. April 1722 in Ulm - 11 August 1794 in Ansbach) was a German composer, flutists and Kapellmeister.
American Moravian music collections contain several thousand pieces by composers as well known as Haydn, Johann Christoph Friedrich Bach, Karl Stamitz; and as little known as Wenzel Pichl, Adalbert Gyrowetz, and Kleinknecht.
