Nabia was the goddess of rivers and water in Gallaecian and Lusitanian mythology, in the territory of modern Galicia (Spain), Asturias (Spain) and Portugal.
The present-day Navia River and Avia (river) in Galicia and Asturias, the Neiva River, near Braga (Bracara Augusta, old Roman capital of Gallaecia) and Nabão River that passes through the city of Tomar may share the etymology.
The goddess Nabia was very popular in the territory of the Callaici Bracari with several inscriptions, like the one at Braga's Fonte do Ídolo (Portuguese for Fountain of the Idol).
