André Joseph Boussart or André Joseph Boussard was a French soldier and general. He enlisted in the army of Habsburg Austria as a youth. A Belgian by birth, he joined the Brabant Revolution against Austria and fled to France when the rebellion collapsed. He soon found himself fighting for France during the French Revolutionary Wars. Promoted to general officer during the French Campaign in Egypt and Syria, he returned to France where he held several non-combat posts.

In the Battle of Prenzlau or Capitulation of Prenzlau on 28 October 1806 two divisions of French cavalry and some infantry led by Marshal Joachim Murat intercepted a retreating Prussian corps led by Frederick Louis, Prince of Hohenlohe-Ingelfingen. In this action from the War of the Fourth Coalition, Hohenlohe surrendered his entire force to Murat after some fighting and a parley. Prenzlau is located about 90 kilometers north of Berlin in Brandenburg.
