Lagny-sur-Marne (pronounced [laɲi syʁ maʁn]; English: Lagny on the Marne) is a commune in the eastern suburbs of Paris, France. It is located in the Seine-et-Marne department in the Île-de-France 26.1 km (16.2 mi) from the center of Paris.

The commune of Lagny-sur-Marne is part of the Val de Bussy sector, one of the four sectors in the "new town" of Marne-la-Vallée.


During the Middle Ages Lagny-sur-Marne was a popular place for tourneys in Northern France. In November 1179 a notable tournament was held by Louis VII of France in honour of the coronation of his son. Later in 1846, Lagny-sur-Marne annexed the commune of Saint-Denis-du-Port.


Inhabitants are called Latignaciens or Laniaques.

Lagny-sur-Marne is served by Lagny – Thorigny station on the Transilien Paris – Est suburban rail line. This station, although administratively located on the territory of the neighboring commune of Thorigny-sur-Marne, lies immediately across the Marne River from the town center of Lagny-sur-marne.


The commune has ten preschools and nine elementary schools.[2] There are two junior high schools, Collège Les 4 Arpents and Collège Marcel Rivière, as well as one senior high school/sixth-form college, Lycée Van Dongen.[3]

Twin towns[edit]

Lagny-sur-Marne is twinned with Sainte-Agathe-des-Monts, Quebec in Canada since 1969, and also Alnwick, Northumberland in England.

Notable residents[edit]

  • It is possible that the Irish family de Lany came from Lagny-sur-Marne.
