Adro (Brescian: Àder) is a town and comune in the province of Brescia, in Lombardy, with a traditional wine-growing vocation favored by its position in the Franciacorta area (northern Italy).

The municipality of Adro is located at the foot of Monte Alto, in Franciacorta about six kilometers from Lago d'Iseo, in the southwestern part of province of Brescia.

[3] From what is reported by Mazza (1986), the origins of the toponym are uncertain: Dante Olivieri claims that it would come from Latin ater or atro ("black", "dark", "obscure"), while Paolo Guerrini suggested the derivation from acer, demonstrating the ancient presence of maple woods.

[3] The town's coat of arms is formed by a capital "A" with a rounded top, of silver color on a green field, which is surrounded by three bunches of grapes with its branches and tendrils.

The following are the most consistent groups:[8] In the local dialect (Brescian [it]) there is the phrase Laurà per la césa de Ader, or to work for the church of Adro.
