The Bezirksliga Rheinhessen-Saar was the highest association football league in the German state of Saarland, the Rheinhessen part of the state of Hesse and parts of the Bavarian region of Palatinate and the Prussian Rhine Province from 1923 to 1927, when the league was replaced by the Bezirksliga Rhein-Saar and the Bezirksliga Main-Hessen.

The Bezirksliga Rheinhessen-Saar, named after the region of Rhenish Hesse (German: Rheinhessen) and the river Saar, started out with eight teams, playing each other in a home-and-away round with the league winner advancing to the Southern German championship, which in turn was a qualification tournament for the German championship.

The winner of this round was awarded the third entry spot for the south to the German finals.

In an attempt to bring all Southern German leagues to a similar system, the Bezirksligas were reorganised in 1927.

The clubs from the Rhenish Hesse region however became part of the Hessen division of the new Bezirksliga Main-Hessen.
