The Battle of Castiglione in Napoleon's first Italian campaigns of the French Revolutionary Wars results in a French victory.

The Battle of Castiglione saw the French Army of Italy under General Napoleon Bonaparte attack an army of the Habsburg monarchy led by Feldmarschall Dagobert Sigmund von Wurmser on 5 August 1796. The outnumbered Austrians were defeated and driven back along a line of hills to the river crossing at Borghetto, where they retired beyond the Mincio River. The town of Castiglione delle Stiviere is located 10 kilometres (6 mi) south of Lake Garda in northern Italy. This battle was one of four famous victories won by Bonaparte during the War of the First Coalition, part of the French Revolutionary Wars. The others were Bassano, Arcole, and Rivoli.

Napoleon Bonaparte, later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815. He led the French Republic as First Consul from 1799 to 1804, then ruled the French Empire as Emperor of the French from 1804 to 1814, and briefly again in 1815. He was King of Italy from 1805 to 1814 and Protector of the Confederation of the Rhine from 1806 to 1813.

The Italian campaigns of the French Revolutionary Wars (1792–1801) were a series of conflicts fought principally in Northern Italy between the French Revolutionary Army and a Coalition of Austria, Russia, Piedmont-Sardinia, and a number of other Italian states.
