Châteauponsac (in French ʃɑtopɔ̃sak/;), also known locally as Château Lorraine, is a commune in the Haute-Vienne department in the Nouvelle-Aquitaine region in western France.
The village lies between the river Semme to the north and the Gartempe to the south, both flowing westward. The Gartempe formed a deep valley, passing below the 12th century church.
Inhabitants are known as Châtelots in French.
Its twelfth-century church is dedicated to Saint Thyrsus.
