Saint-Romain (French pronunciation: [sɛ̃ ʁɔmɛ̃]) is a commune in the Charente department in southwestern France.

The commune is located in the south of the department, 1 km west of Aubeterre-sur-Dronne, 9 km north of Saint-Aulaye, 19 km west of Ribérac, 18 km south of Montmoreau and 48 km south of Angoulême.

In terms on surface area, Saint-Romain is the largest commune of its canton, spreading up to 200m of Aubeterre town center. The commune sits on a low Cretaceous limestone plateau.

No rivers traverse Saint-Romain, but two small tributaries have their sources there: the Beauronne which flows south-west into the Dronne river and a tributary of the Tude in the north, as well as the Écrevansou, a small spring that follows the commune's eastern limits.
