Valmy (French pronunciation: [valmi]) is a rural commune in the Marne department in the Grand Est region in Northeastern France.

The town stands on the west flank of the Argonne massif, midway between Verdun and Paris, near Vouziers.

Valmy provided the setting for the Battle of Valmy on 20 September 1792.

The largest ship-of-the-line ever constructed, the Valmy, was named after this battle.
