Agliano Terme borders the following municipalities: Calosso, Castelnuovo Calcea, Costigliole d'Asti, Moasca, and Montegrosso d'Asti. Traditionally called simply Agliano (or in Piemontese), the "Terme" was added in recent times to draw attention to the presence of thermal baths, a tourist attraction.
