The siege of Hainburg was a two-siege of Hainburg conducted by Matthias I, King of Hungary, during the Austro-Hungarian War (1477–88). The first siege was broken in July 1482 by the Imperial Army of the Holy Roman Empire. Corvinus laid siege to the town again in August 1482, this time with better preparations, and took Hainburg in September 1482.
