Marne (French pronunciation: [maʁn]) is a department in the Grand Est region of France. It is named after the river Marne which flows through it. The prefecture (capital) of Marne is Châlons-en-Champagne (formerly known as Châlons-sur-Marne). The subprefectures are Épernay, Reims, and Vitry-le-François.
The Champagne vineyards producing the world-famous sparkling wine are located within Marne.
The department is named after the Marne, which was called Matrona in Roman times.
Marne has a long association with the French Army. The training ground of the Camp Militaire de Mailly straddles the border with the département of Aube in the south while that of the Camp de Mourmelon occupies a large area north of Châlons-en-Champagne. The smaller Camp de Moronvilliers lies to the east of Reims and the Camp Militaire de Suippes lies to the east of that. These are all on the chalk of the Champagne plateau, a feature comparable in geology but not size, with the British military training ground on Salisbury Plain.
Rivers draining the department include the Marne, Vesle, Ardre and Somme-Soude. Numerous other rivers, such as the Grande and the Petite Morin rise in the department but flow mainly in others. Conversely, the Aube joins the Seine in the department of Marne.
The inhabitants of the department are called Marnais.

Reims, with its famous cathedral in which the kings of France were traditionally crowned, is a major attraction. Other branches of tourism are provided by the bird reserve on the Lake Der-Chantecoq and the fishing lakes nearby. The Parc Naturel Régional de la Montagne de Reims is a major area of country recreation. In the west of the département there are many scenic routes to be explored as also are the several wine cellars of Épernay.
