Marainville-sur-Madon (French pronunciation: [maʁɛ̃vil syʁ madɔ̃] ⓘ, literally Marainville on Madon) is a commune in the Vosges department in Grand Est in northeastern France.

It is the last commune traversed by the Madon before that river continues north into the adjacent département of Meurthe-et-Moselle.

The land is devoted to agriculture: there is no longer any forest in the commune.

[3] Michał Jan Pac (1730-1787), a Polish nobleman exiled after the defeat of the Bar Confederation, bought the castle and Marainville in 1780;[4] his steward, Adam Weydlich, made acquaintance with the village syndic, François Chopin.

After Pac's death, the Weydlichs left France for Poland, and Nicolas Chopin emigrated with them; in 1810, his better known son, Frédéric Chopin, was born in the Polish village of Żelazowa Wola.
