Château de Clairvaux, Renaissance castle in Scorbé-Clairvaux, France.

Château de Clairvaux is a private castle in Scorbé-Clairvaux, in the Vienne department, begun at the very start of the 16th century and among the earliest Renaissance buildings in Poitou. Its long three-storey main block has rows of tall windows and dormers, a taller tower with a steep conical roof and lantern, and a shorter round tower beside it. A moat and a long white wall with a corner turret border it in front.

Renaud Chabot built a new castle near the fairground after a 1470 quarrel with Christophe de la Tour Landry. In 1580 René de Villequier, governor of Paris, bought both Clairvaux estates, had the seigneurie raised to a county, and added a monumental entrance with two square pavilions. César d'Aumont obtained a marquisate by letters patent of Louis XIII in 1620.

The castle houses a chess museum featuring collections from different regions, including a set used during Napoleon's campaigns. Visitors can see how this strategic game was played across various cultures and time periods.

The castle stands in the village centre on the square now named place Étienne Chérade de Montbron, with the moat and the long white wall with its corner turret bordering the front. The building is a private property, so visits depend on the owner's opening; the chess museum and the permanent exhibition on Henri III are inside. The rooms and grounds are seen on foot.

René de Villequier, governor of Paris and a favourite of Henri III, helped the king escape the Royal Palace of Kraków after the death of Charles IX. A room in the castle's great tower is named after him, and a carved balcony there is attributed to the Renaissance architect Philibert Delorme.
