Barr (French pronunciation: [baʁ] ⓘ; in Alsatian Borr) is a commune in the Bas-Rhin department in the Alsace region of north-eastern France.

La Kirneck river rises in the west of the commune and flows eastwards through the town and continues east to join the Andlau.

It is the subject of a "close to nature forestry" management according to the principles recommended by Prosilva with no clear-felling.

Barr was originally an imperial property, but in 1522 the Habsburgs leased it to Nicolas Ziegler, and converted into Allod or freehold three years later.

[9] During the Thirty Years War it suffered from the Holy Roman Empire, the Swedes, and the French but less than the surrounding villages.

In 1763 a first decision attributed the lands to Strasbourg; there was an appeal and it was not until 1836, under the July Monarchy, that the verdict was definitively confirmed.

The portcullis in the arms symbolizes the ancestral role of this city as the last barrier on the way to the Mont Sainte-Odile, formerly a sacred place occupied by the Druids.
