Berzo Inferiore (Camunian: Bèrs) is an Italian comune of 2,316 inhabitants in Val Camonica, province of Brescia, in Lombardy, northern Italy.

The village of Berzo Inferiore (Inferiore means "at the bottom" to distinguish from Berzo Demo) is situated in Val Grigna, a side valley of the Oglio valley, upstream from Esine and downstream from Bienno.

The area has known habitation dating back to Mesolithic prehistory, as ascribed from artifacts found near Passo Crestoso. The first documentation of the town name is in a document from 1041, that mentions Bercio. Documents also cite a quarrel with the nearby town of Bovegno regarding pastoral lands. In 1350, the bishop of Brescia, Zanino Federici of Gorzone, asserted feudal rights for the territories of the Lower Berzo, Ono and Cricolo and Cerveno of Rainaldo.
