Vierves-sur-Viroin (French pronunciation: [vjɛʁv syʁ viʁwɛ̃], lit.

'Vierves on Viroin'; Walloon: Viêpe) is a village of Wallonia and a district of the municipality of Viroinval, located in the province of Namur, Belgium.

The village surrounds the castle, which was erected during the Middle Ages.

Its present appearance dates large from the end of the 18th century, as it was extensively ravaged by fire in 1775 and later restored.

Aside from the castle, the village has an ancient lavoir and ruins of a mill from the 13th–14th centuries.
