Forbach is a commune in the department of Moselle in the northeastern French Region of Grand Est.
It is located on the German border approximately 15 minutes from the center of Saarbrücken, Germany, with which it constitutes a cross-border conurbation, and is part of the Saar-Moselle Eurodistrict. According to the 2011 national census, Forbach had a population of 21,954 inhabitants, which, including its greater urban area, makes it the largest town in the eastern Moselle area.
Before the Schengen Treaty, Forbach was a major border crossing at which customs procedures were carried out, both for road and for rail transport and travel. Here, trains also change track sides from right-hand running to left-hand running.
