Reisbach is a small town, belonging to the district of Saarlouis in the Bundesland Saarland.

The village was formed on April 1, 1937, when the two townships of Reisweiler and Labach were joint together as "Reisbach".

The first written documentation about Labach stems from the 13th century, when it was known under the name "Loupach" or "Loupbach".

In 1212, Count Heinrich of Zweibrücken gave his ownership of the villages Reisweiler and Labach to Fraulautern Abbey.

Labach belonged to the lordship of Schwarzenholz, and thus Fraulautern Abbey, until 1792, when the French Revolution changed everything.
