The Battle of Teugen-Hausen or the Battle of Thann was an engagement that occurred during the War of the Fifth Coalition, part of the Napoleonic Wars. The battle was fought on 19 April 1809 between the French III Corps led by Marshal Louis-Nicolas Davout and the Austrian III Armeekorps commanded by Prince Friedrich Franz Xaver of Hohenzollern-Hechingen. The French won a hard-fought victory over their opponents when the Austrians withdrew that evening. The site of the battle is a wooded height approximately halfway between the villages of Teugn and Hausen in Lower Bavaria, part of modern-day Germany.

Also on 19 April, clashes occurred at Arnhofen near Abensberg, Dünzling, Regensburg, and Pfaffenhofen an der Ilm. Together with the Battle of Teugen-Hausen, the fighting marked the first day of a four-day campaign which culminated in the French victory at the Battle of Eckmühl.

Austria's invasion of the Kingdom of Bavaria caught Emperor Napoleon I of France's Franco-German army by surprise. Though the advance of Archduke Charles' Austrian army was slow, mistakes by Napoleon's subordinate Marshal Louis-Alexandre Berthier placed Davout's corps in great peril. As Davout withdrew southwest from Regensburg on the south bank of the Danube, Charles tried to intercept the French with three powerful attacking columns.
