The Battle of Neuburg occurred on 27 June 1800 in the south German state of Bavaria, on the southern bank of the Danube river. Neuburg is located on the Danube between Ingolstadt and Donauwörth. This battle occurred late in the War of the Second Coalition (1798–1802), the second war between Revolutionary France and the conservative European monarchies, which included at one time or another Britain, Habsburg Austria, Russia, the Ottoman Empire (Turkey), Portugal and Naples. After a series of reverses, several of the allies withdrew from the Coalition. By 1800, Napoleon's military victories in northern Italy challenged Habsburg supremacy there. French victories in the upper Danubian territories opened a route along that river to Vienna.

Palatinate-Neuburg was a territory of the Holy Roman Empire, founded in 1505 by a branch of the House of Wittelsbach. Its capital was Neuburg an der Donau. Its area was about 2,750 km2, with a population of some 100,000.
