Berschweiler bei Kirn is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Birkenfeld district in Rhineland-Palatinate, Germany. It belongs to the Verbandsgemeinde Herrstein-Rhaunen, whose seat is in Herrstein. Berschweiler bei Kirn is one of two municipalities in the district with the name Berschweiler. The two are distinguished from each other by their geographical “tags”; the other one is called Berschweiler bei Baumholder.

The municipality lies west of the Nahe between Kirn and Herrstein. Berschweiler bei Kirn lies roughly 8 km north of Idar-Oberstein and 5 km west of Kirn. Almost half the municipal area is wooded.

• Agriculture 44.2%
• Woodland 48.4%
• Open water 0.2%
• Settlement and transport 6.9%

The council is made up of 6 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman.

Berschweiler's mayor is Hubert Paal.

The municipality's arms might be described thus: Per bend azure a bear's head sinister erased Or langued gules and Or a lion rampant of the third armed and langued of the first.

The charge on the sinister (armsbearer's left, viewer's right) side is the lion borne as an heraldic device by the Waldgraves and Rhinegraves, who held the village in the Middle Ages. The charge on the dexter (armsbearer's right, viewer's left) side, a bear's head, is canting. “Bear” is Bär – both words are pronounced rather similarly – in German, which sounds like the first three sounds in “Berschweiler”.

The arms have been borne since 16 May 1962.
