Martinvelle (French pronunciation: [maʁtɛ̃vɛl] ⓘ) is a commune in the Vosges department in Grand Est in northeastern France.

The intersection of the 48th parallel north with the 6th meridian east lies within the commune.

The village's history is more linked with that of the adjacent Franche-Comté than that of Lorraine.

Until the French Revolution the lords of Passavant ruled here.

The coat of arms includes images of an oak leaf and of a mechanical hay rake, reflecting the importance here both of the forest and of agriculture, and recalling the factory that manufactured agricultural implements locally between 1860 and 1962.
