The department is surrounded by the French departments of Meuse, Marne, and Aisne and by Belgium on the north.
Situated in the Ardennes uplands on the border with Belgium, the department of Ardennes includes many areas of very dense woodland.
The principal river is the Meuse River.
The Ardennes is otherwise relatively sparsely populated.
The Eifel range in Germany adjoins the Ardennes and is part of the same geological formation, although they are conventionally regarded as being two distinct areas.
