The siege of Mantua ends after eight months when Count Dagobert Sigmund von Wurmser surrenders the fortress of Mantua to Napoleon Bonaparte. The fall of Mantua secures French control over Northern Italy and marks the beginning of the conclusion of the Italian campaign of 1796-1797, and sets the stage for the end of the War of the First Coalition.

The siege of Mantua lasted from 4 June 1796 to 2 February 1797 with a short break where French forces under the overall command of Napoleon Bonaparte besieged and blockaded a large Austrian garrison at Mantua for many months until it surrendered. The siege was the focal point of the Italian Campaign of 1796-1797, lasting the vast majority of the campaign and being the hinge point that would determine which side would control Northern Italy. The eventual surrender, together with the heavy losses incurred during four unsuccessful relief attempts, led to Napoleon invading Austria and convincing the Austrians to sue for peace in 1797. The siege occurred during the War of the First Coalition, which is part of the French Revolutionary Wars. Mantua, a city in the Lombardy region of Italy, lies on the Mincio River.
