The Battle of Turnhout (October 27, 1789) is a battle that takes place in the town of Turnhout (today in Belgium) between Habsburg Austria and a Belgian émigré (Patriot) army commanded by Jean-André van der Mersch which had recently invaded from the nearby Dutch Republic.
The battle is one of the pivotal moments of the Brabant Revolution and the Patriots' unlikely victory leads to the expulsion of Austrian forces to Luxembourg from the Southern Netherlands for nearly a year.
