L'École Nationale Supérieure d'Horticulture ("Ecole Nationale Supérieure d’Horticulture de Versailles", "Ecole Nationale d’Horticulture") was a French "grande école" of horticulture founded in 1874 to promote French agricultural education (Under the Act of 16 Dec. 1873).
 It was an initiative of Pierre Joigneaux and the first Director was Auguste Hardy.
 The school was located in the “Potager du Roi” (the King’s kitchen garden) in Versailles where the former "Institut National Agronomique" had been established in October 1848 at the end of the Second Republic.
 At first it was named "Ecole Nationale d’Horticulture", being changed to "Ecole Nationale Supérieur d’Horticulture" (ENSH) in 1961.
 In 1976, the "Ecole Nationale Supérieure du Paysage" (ENSP) was separated from the ENSH, and both remain located at the Potager du Roi.
 In 1995, the ENSH was transferred to Angers, while the ENSP remained at Versailles.
 Three year later, the ENSH was officially combined with the national school of practitioners of horticulture and landscape ("Ecole National des Ingénieurs de l’Horticulture et du Paysage" ENITHP) in Angers to produce the Institut National d'Horticulture et de Paysage ("National Institute for Horticulture and Landscape Management").
