Saint-Péray (French pronunciation: [sɛ̃ peʁɛ] ⓘ; Occitan: Sant Pèire d'Ai) is a commune in the Ardèche department in the Auvergne-Rhône-Alpes region in southern France.

Historically part of the royal province of Vivarais, it has been a significant settlement since the 15th century when inhabitants moved from the fortified castle of Crussol to the valley of Mialan.

The commune is characterized by its geological features, primarily composed of sedimentary layers that support a diverse Mediterranean flora and fauna, despite its relatively high latitude.

The local vineyards primarily cultivate the Roussanne and Marsanne grape varieties, producing wines with a pale yellow hue and floral aromas.

Saint-Péray has preserved its cultural heritage through various communal activities and partnerships with other European towns, including Groß-Umstadt in Germany and Santo Tirso in Portugal.
