Château de Jossigny, 18th-century French castle in Jossigny, France.

Château de Jossigny is an 18th-century castle with three main pavilions and two side wings containing a chapel and kitchen. The buildings are arranged around a central courtyard with various outbuildings.

The castle was built in 1753 for a parliamentary counselor and designed by a royal architect. It represents a significant period in French architecture during the 18th century.

The name Jossigny comes from the medieval land held by Cyprien de Freil, who sold it to Pierre d'Orgemont on 4 November 1359. The Leconte des Graviers family, parliamentary nobility, kept the estate until 1975. The rocaille interior decoration was identified as the work of ornamentist Nicolas Pineau, whose Chinese-style designs for the ground-floor salon match the pagoda roof.

The château lies 32 km east of Paris and 6 km south of Lagny-sur-Marne, in the commune of Jossigny, Seine-et-Marne. It has belonged to the Centre des monuments nationaux since 1975 and is managed with the conservation team of the château de Champs-sur-Marne. The building, its outbuildings, park and avenues have been classified as monuments historiques since 23 December 1942.

The central pavilion's roof is shaped like a pagoda, echoing the chinoiserie decoration Nicolas Pineau designed for the ground-floor salon. The broken pediment of the projecting bay, with an oculus between its volutes, is another rocaille detail to look for. The same Pineau clasp motifs appear on the comtesse d'Argenson's house at Montreuil.
