The Marne (/mɑːrn/; French pronunciation: [maʁn] ) is a river in France, an eastern tributary of the Seine in the area east and southeast of Paris. It is 514 kilometres (319 mi) long. The river gave its name to the departments 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. Its main tributaries are the Rognon, the Blaise, the Saulx, the Ourcq, the Petit Morin and the Grand Morin.
