Niederbronn-les-Bains (French pronunciation: [nidəʁbʁɔn le bɛ̃]; German: Bad Niederbronn) is a commune in the Bas-Rhin department in Grand Est in north-eastern France.

During the fifth century the little town fell victim to the violence that accompanied the period of intense migrations that followed the disappearance from the western empire of Roman governance.

The spa tradition today supports a more general tourist industry in the little town, which even boasts its own casino.

A meeting place called the Albert Schweitzer Centre was set up in 1993 to foster contacts between French and German young people.

Other nearby attractions in the area include the ruined Wasenbourg and the look-out tower on the Grand Wintersberg, some four kilometers to the north.
