Charleville-Mézières (French pronunciation: [ʃaʁ.lə.vil.me.zjɛʁ]) is a commune in northern France, capital of the Ardennes department in the Champagne-Ardenne region. Charleville-Mézières is located on the banks of the Meuse River.

The commune of Charleville-Mézières was created in 1966 by the administrative grouping of five former communes, which already formed a single agglomeration. These communes were: Charleville, Étion, Mézières (former préfecture), Mohon and Montcy-Saint-Pierre. Another commune, Le Theux, had already been included into Mézières in 1965. It has a population of about 51,000.

A marionette festival (French: Le festival des marionnettes) has been held there every three years since 1961. However, starting from 2011 marks its transition to a biennial event. There is also a giant marionette incorporated into a building, displaying a little show every 15 minutes when working normally.

The poet Arthur Rimbaud (1854–1891) was born in Charleville. The Musée Rimbaud (Rimbaud museum) is located in the old water mill (Le Vieux Moulin) to the north of the town.
