A Rúa is a mostly rural municipality in the province of Ourense, in the autonomous community of Galicia, Spain.

The Cereixido hills are on the northern part of the municipality, with Cabeza Porriñas (1.221 m) as its highest point.

According to Pliny the Elder, before the arrival of the Romans, A Rúa and the rest of the comarca of Valdeorras was occupied by the Celtiberian Cigurri tribe (also known as the Egurri).

[6] The comarca of Valdeorras was depopulated after its capture by Alfonso I as part of the Desert of the Duero, a buffer zone he created between Asturias and the Muslim states.

The opening of the Palencia–A Coruña railway line on 1 September 1883 was a decisive moment for the economy of the region.

Since ancient times Valdeorras has been a wine-producing region due to its climate and position on the river Sil.
