The Napoleonic Kingdom of Italy (Italian: Regno d'Italia, but also Regno Italico) was a kingdom founded in Italy by Napoleon, in 1805. The kingdom ended in 1814, with the defeat of Napoleon.

The Kingdom of Italy was born on 17 March 1805. On that day, the Italian Republic, whose president was Napoleon, become Kingdom of Italy, with Napoleon as King of Italy and Eugène de Beauharnais viceroy. Napoleon was crowned in Milan's cathedral, on 26 May 1805, with the Iron Crown of Lombardy.

The Kingdom consisted of Lombardy, Venetia, Duchy of Modena, part of Papal States (Ancona, the remaining part with Rome had been annexed to French Empire), part of Kingdom of Sardinia, South Tyrol.

Napoleon abdicated on 11 April 1814. Eugène tried to become king of Italy, but the opposition of the Senate of the Kingdom and Milan insurrection (20 April 1814) failed his plan: Eugène was exiled by the Austrians, who occupied Milan.
