Jacques Bittner (ou Jacob Büttner, fl. 1680) was a lutenist and composer of Austro-Bohemian origin. He published 170 pieces for lute in Nuremberg in 1682 and 1683. The second collection of Bittner's music published in 1683 under the German title, Galantheste Methode die Laute zu traktieren, is considered lost to date.
The 18th century lutenist Ernst Gottlieb Baron described Bittner briefly in his 1727 Untersuchung des Instruments der Lauten. According to Baron, Bittner's music was composed "according to the latest and most galant method of playing the lute at that time".
