The Bezirksliga Rhein-Saar was the highest association football league in the German state of Saarland, the Bavarian region of Palatinate and the northernmost part of Baden from 1927 to 1933.

The clubs in each division played each other in a home-and-away round with the division winners advancing to the Southern German championship, which in turn was a qualification tournament for the German championship.

The leagues were reduced to nine teams each in the following season but remained unchanged in modus otherwise.

With the rise of the Nazis to power, the Gauligas were introduced as the highest football leagues in Germany.

In the region, the Gauliga Südwest/Mainhessen replaced the Bezirksliga Rhein-Saar as the highest level of play.
