The Ligurian Republic or Republic of Liguria was a French client republic formed by Napoleon on 14 June 1797. It consisted of the old Republic of Genoa, which covered most of the Ligurian region of Northwest Italy, and the small Imperial fiefs owned by the House of Savoy inside its territory. Its first Constitution was promulgated on 22 December 1797, establishing a directorial republic. The directory was deposed on 7 December 1799 and the executive was temporarily replaced by a commission. In 1802, a doge was nominated for a 5-year term, according to the second Constitution imposed by Napoleon, and a Senate was established.

The Republic of Genoa was a medieval and early modern maritime republic from the years 1099 to 1797 in Liguria on the northwestern Italian coast. During the Late Middle Ages, it was a major commercial power in both the Mediterranean Sea and the Black Sea. Between the 16th and 17th centuries, it was one of the major financial centers in Europe.
