The Battle of Mühldorf (also Battle of Ampfing) was fought near Mühldorf am Inn on September 28, 1322 between the Duchy of (Upper) Bavaria and Austria. The Bavarians were led by the German king Louis of Wittelsbach, while the Austrians were under the command of his cousin, the anti-king Frederick of Habsburg.

The early 14th century saw the powerful dynasties of Habsburg, Luxembourg and Wittelsbach rivaling for the rule over the Holy Roman Empire, while the prince-electors were anxious not to allow one noble family to install a hereditary monarchy. After the death of Emperor Henry VII of Luxembourg in 1313, the electoral college denied the succession of his son John of Bohemia and instead accorded its favor to Louis of Wittelsbach and Frederick of Habsburg, but were split over the question of whom to choose.

Therefore, in 1314 a double election took place at Frankfurt. Cologne, the Electorate of the Palatinate, Bohemia and the Duchy of Saxe-Wittenberg voted for Frederick as Rex Romanorum. Mainz, Archbishopric of Trier, Brandenburg and Elector John II of Saxe-Lauenburg (whose electoral dignity was denied by their Saxe-Wittenberg cousins) adopted Louis.
