The Battle of Ebelsberg, known in French accounts as the Battle of Ebersberg, was fought on 3 May 1809 during the War of the Fifth Coalition, part of the Napoleonic Wars. The Austrian left wing under the command of Johann von Hiller took up positions at Ebersberg on the Traun river. The French under André Masséna attacked, crossing a heavily defended 550-meter-long bridge and subsequently conquering the local castle, thus forcing Hiller to withdraw. Ebelsberg is now a southern suburb of Linz, situated on the south bank of the Traun, a short distance above the place where that stream flows into the Danube River.

The War of the Fifth Coalition was a European conflict in 1809 that was part of the Napoleonic Wars and the Coalition Wars. The main conflict took place in Central Europe between the Austrian Empire of Francis I and Napoleon's French Empire. The French were supported by their client states—the Kingdom of Italy, the Confederation of the Rhine and the Duchy of Warsaw. Austria was supported by the Fifth Coalition which included the United Kingdom, Portugal, Spain, and the Kingdoms of Sardinia and Sicily, although the latter two took no part in the fighting. By the start of 1809 much of the French army was committed to the Peninsular War against Britain, Spain and Portugal. After France withdrew 108,000 soldiers from Germany, Austria attacked France to seek the recovery of territories lost in the 1803–1806 War of the Third Coalition. The Austrians hoped Prussia would support them, having recently been defeated by France, but Prussia chose to remain neutral.
