Italian Republic (It: Repubblica Italiana) was the name taken by the former Cisalpine Republic of north-central Italy in 1802, following the change in its constitution that allowed French First Consul Napoleon Bonaparte to become its president.

Italian Republic consisted of the same areas the had made up the Cisalpine Republic – primarily Lombardy and the Romagna. In 1805, following Bonaparte's assumption of the title of Emperor of the French, it was transformed into the Kingdom of Italy (Regno d'Italia), with Napoleon as King and his nephew Eugène de Beauharnais as Viceroy.
