The Army of Italy was a field army of the French Army stationed on the Italian border and used for operations in Italy itself. Though it existed in some form in the 16th century through to the present, it is best known for its role during the French Revolutionary Wars and Napoleonic Wars.

The Battle of Sacile on 16 April 1809 and its companion Clash at Pordenone on 15 April saw an Austrian army commanded by Archduke John of Austria defeat a Franco-Italian army led by Eugène de Beauharnais and force it to retreat. Sacile proved to be the most notable victory of John's career. The action took place east of the Livenza River near Sacile in modern-day Italy during the War of the Fifth Coalition, part of the Napoleonic Wars.
