Certaldo (Italian pronunciation: [tʃerˈtaldo]) is a town and comune (municipality) of Tuscany, Italy, in the Metropolitan City of Florence, located in the middle of Valdelsa.

It is also the birthplace of actor Ernesto Calindri and of coach Luciano Spalletti, who has been the manager of Italy national football team since 2023.

Certaldo had Etruscan-Roman origins, as shown by the numerous archaeological finds that are scattered around the city's territory, including ceramics, utensils and Etruscan tombs, some of which were found just recently.

[5] The Etruscan origins were discovered mostly thanks to the toponymy of some localities and streams, for example the Agliena and the Elsa river (which flow near Certaldo), and the foodstuffs deposits in the hills.

All of the finds of Etruscan-Roman origin are today kept in the ground floor of the Palazzo Pretorio, in the medieval part of the town.
