The Doge of Genoa was the head of state of the Republic of Genoa, a city-state and soon afterwards a maritime republic, from 1339 until the state's extinction in 1797. Originally elected for life, after 1528 the Doges were elected for terms of two years. The Republic was ruled by a small group of merchant families, from whom the doges were selected.

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.
