The Kingdom of Italy (18051814; Italian: Regno d'Italia; French: Royaume d'Italie) was a kingdom in Northern Italy (formerly the Italian Republic) in personal union with France under Napoleon I. It was fully influenced by revolutionary France and ended with Napoleon's defeat and fall. Its government was assumed by Napoleon as King of Italy and the viceroyalty delegated to his step-son Eugne de Beauharnais. It covered Savoy and the modern provinces of Lombardy, Veneto, Emilia-Romagna, Friuli Venezia Giulia, Trentino, South Tyrol, and Marche. Napoleon I also ruled the rest of northern and central Italy in the form of Nice, Aosta, Piedmont, Liguria, Tuscany, Umbria, and Lazio, but directly as part of the French Empire, rather than as part of a vassal state.

The Italian Republic (Italian: Repubblica Italiana) was a short-lived (1802–1805) republic located in Northern Italy. Napoleon Bonaparte served as president and its capital was Milan.
