Pereiro

Pereiro is a toponym of Iberian origin. The best-known use is Pereiro de Aguiar, a municipality in the province of Ourense, within the autonomous community of Galicia, Spain. Located in the northwestern part of the country, Pereiro de Aguiar encompasses a rural region with small villages, rolling hills, and agricultural activity. The local economy historically relies on farming and livestock, with services and small-scale manufacturing contributing to employment. The population is in the low thousands, and the municipality is part of Galicia’s tradition of parishes and rural settlements.

The name Pereiro derives from the Galician-Portuguese word for a pear tree, reflecting the region’s orchard heritage and the common practice of naming places after vegetation or land use.

Beyond Pereiro de Aguiar, the toponym is used for other smaller localities in Galicia and Portugal and appears as a surname in Iberian communities. The term also features in historical and cultural references tied to the broader Galician-Portuguese linguistic area.
