Zas is a municipality in the province of A Coruña, within the autonomous community of Galicia in northwestern Spain. It forms part of the comarca (county) of Terra de Soneira.
As a Galician municipality rather than a large urban centre, Zas comprises a scattered collection of parishes and small settlements typical of the region's rural administrative structure. Its location in the Terra de Soneira places it within the broader cultural and geographic context of Galicia, a region known for its distinct language, Atlantic coastline, and hilly inland terrain.
