Haras de Jardy, Horse stud farm in Marnes-la-Coquette, France.

Haras de Jardy is a 75-hectare park of meadows and woods at the edge of the Fausses Reposes state forest in Marnes-la-Coquette. Edmond Blanc built its Anglo-Norman-style stables from 1889, keeping only an older barn; the complex included 115 boxes, 10 stalls, a riding hall and the "Cour des 49". It is now a multi-sports park centred on riding, with a golf course and the country's largest equestrian centre.

A priory dependent on the abbey of Tiron is documented at Jardy from 1120, and its lands were sold as national property in 1791. In 1889 Edmond Blanc bought the estate, demolished most of the buildings and built an Anglo-Norman stud farm with 115 boxes and the Cour des 49. Marcel Boussac bought it in 1943; the state acquired it in December 1979 and it opened to the public in 1981.

The name Jardy derives from the old forest where a small Benedictine priory, dependent on Tiron Abbey, is documented from 1120; a church, Saint-Jean-Baptiste de Jardies, appears in a 1147 document. The priory was never large, more a small farm whose monks leased the fields to tenant farmers. Its lands were sold as national property in 1791.

The park opened to the public in 1981 and was bought by the Conseil général des Hauts-de-Seine in November 2006. It lies at the edge of the Fausses Reposes state forest, about 10 minutes by car from Porte d'Auteuil and from the château de Versailles, close to the Vaucresson exit of the A13. The A13 cut off the northern part of the estate; two former gate lodges there now serve as shops.

The property received visits from King Edward VII, Queen Elizabeth II, and Soviet leader Nikita Khrushchev during its peak years, underscoring its global reputation. These high-profile visits demonstrated the facility's importance in international horse breeding circles.
