Jean II de Sarrebruck-Commercy

Jean II de Sarrebruck-Commercy (died 1344) was a younger son of Jean I, count of Saarbrücken and lord of Commercy, and Mahaut d'Apremont. He inherited the castle of Commercy as sire of Commercy-Château-Haut, while his nephew Jean IV kept the county of Saarbrücken and the Château-Bas portion of the town. In 1324 he and his father granted Commercy its charter of franchises.

In 1331 he married Alix de Joinville, heiress of Briquenay and Vénizy, who brought him those Champagne lordships. Their sons Simon II and Jean III later ruled Commercy.
