Leuville-sur-Orge (French pronunciation: [løvil syʁ ɔʁʒ] ⓘ, literally Leuville upon Orge) is a commune 31 km (19 mi) south of Paris, France.

During the famous battle of Montlhéry (13 July 1465) between Louis XI and Charles le Téméraire, the population of Leuville (approximately 50) was halved.

During the French Revolution (1789–1799), Leuville served as a refuge for Lacépède, protégé of Buffon and a knowledgeable botanist, whilst fleeing the reign of terror in Paris.

This was helped by its location on the «Voie Royale», a major road connecting Orléans and Paris which gave easy access to the nation's capital.

Produce was originally transported by foot, then by cart, and eventually by train, thanks to the famous Arpajonnais railroad.
