Jamu Mare (Hungarian: Nagyzsám; German: Freudenthal or Großscham; Serbian: Велики Жам, romanized: Veliki Žam) is a commune in Timiș County, Romania.

It is composed of five villages: Clopodia, Ferendia, Gherman, Jamu Mare (commune seat), and Lățunaș.

The administration moved the Romanians to the border area, and the houses were assigned to the Germans.

At the end of the 18th century, Hungarian statistician Elek Fényes [hu] recorded that the village called Nagy-Zsám had a population of 1,562 and belonged to the nobleman László Karácsonyi.

[8] Jamu Mare is now a railway terminus, but between 1925 and 1930, trains would pass through it all the way to Vršac in present-day Serbia.
