The Marne is a river in France, a tributary of the Seine in the area east and southeast of Paris. It is about 525 km (326 mi) long. The river gave its name to the départements of Haute-Marne, Marne, Seine-et-Marne, and Val-de-Marne.

The Marne starts in the Langres plateau, runs generally north then bends west between Saint-Dizier and Châlons-en-Champagne, joining the Seine at Charenton just upstream from Paris.

In the Champagne région part of the water is led through the artificial lake Lac du Der-Chantecoq, in order to regulate the water discharge. This way large inundations or low river levels downstream are prevented.

The Marne River was the site of two battles during the First World War. The first battle was the turning point of World War I, fought in 1914. The second battle was fought four years later, in 1918.

During the 19th and 20th centuries, the Marne inspired many painter artists among whom:

• Camille Corot
• Paul Cézanne
• Camille Pissarro
• Henri Rousseau, dit " Le Douanier Rousseau"
• Albert Marquet
• Raoul Dufy
• André Dunoyer de Ségonzac
• Louis Vuillermoz
• Maurice Boitel
• Daniel du Janerand
