Pietro Fregoso (or Campofregoso; 1330 – 22 April 1404) was a statesman who became the 13th Doge of Genoa, serving only a single day in 1393 before ceding the dogeship.

Pietro became bachelor of law and joined the family's business involved in trade with the Orient.

On the political scene, he obtained a number of positions including the role of Podestà of the city of Novi and, in 1373, he became admiral of the Republic and was in charge of the conquest of Cyprus.

[1] After this short episode, Pietro continued his political career, in particular as member of the Council of the commune until his death on 22 April 1404.

His daughter Pomellina was regent of Monaco on behalf of her granddaughter, Claudine Grimaldi.
