Hollabrunn (German pronunciation: [hɔlaˈbʁʊn] ⓘ) is a district capital town in the Austrian state of Lower Austria, on the Göllersbach river.

one of the most significant La Tène culture cities in central Europe briefly flourished on the southern slopes of the Sandberg hill at Roseldorf close to the village of Platt, a few kilometers to the northwest of Hollabrunn.

During the War of the Third Coalition, the nearby town of Schöngrabern on 16 November 1805 was the site of a battle between the French Napoleonic troops under Joachim Murat (including general Nicolas Oudinot, who was wounded) and the Russian general Pyotr Bagration (who was protecting Kutuzov's retreat north towards Austerlitz).

Almost four years later during the War of the Fifth Coalition, the town once more saw two battles between French and Austrian troops.

The Battle of Hollabrunn was a rearguard action fought after the battle of Wagram on 9 July 1809 by the Austrian VI Korps under Johann von Klenau against elements of the French IV Corps, under the command of André Masséna.
