The Treaty of Pisa was signed in 1438 to end the war of Neapolitan Succession, which started in 1437 with the death of Charles IV of Naples and ended in 1438 with the Rape of Genoa and the defeat of the allied armies at Turin in late 1437.

After the decisive battle of Turin, Niccolò Maria, one of the claimants to the Neapolitan crown and Grand Duke of Milan, invited diplomats from Castile, Burgundy, and France to Pisa to negotiate a peace treaty. It was clear that Milan would retain Naples, but Genoa's sack led to its partition at Pisa.
