The territory falls in and makes up the largest part of the historical region ofTuscia, with the name sometimes being used synonymously with that of the province.

The territory of the Province of Viterbo can be roughly divided into four geographical areas:
the coastal and flat area of the Lazio Maremma;
the Alta Tuscia, which is more hilly and has a volcanic origin, corresponding to the areas near Tuscany and Lake Bolsena;
the area of the Cimini Mountains around Lake Vico and the regions bordering the metropolitan city of Rome;
lastly, the eastern part bordering Umbria, encompassing the areas bathed by the Tiber River.
It can be said that the city of Viterbo geographically belongs both to the Alta Tuscia and the Cimini area, as it is located right below the mountains, yet at a short distance from Lake Bolsena.
