The Bezirksliga Rhein-Saar was the highest association football league in the German state of Saarland, the Bavarian region of Palatinate and the northern-most part of Baden from 1927 to 1933. The league was disbanded with the rise of the Nazis to power in 1933.
The league operated from the start in two regional divisions, the Rhein-division, named after the river Rhein and the Saar-division, named after the river of Saar. The first played with eleven, the second with ten clubs in its first season 1927-28. 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. A Bezirksliga final was not played.
The second and third placed team in each division qualified for another round, the Bezirksliga runners-up round, to determined one more team which would gain entry to the German finals.
The leagues were reduced to nine teams each in the following season but remained unchanged in modus otherwise. For the 1929-30 season, both divisions then operated on a strength of eight teams, a system that also applied in the following season.
In the 1931-32 season, both divisions expanded in strength to ten teams. The Southern German finals were also reorganised with the top two teams from each division advancing to the Northwest finals group.
In its last season, 1932-33, both divisions operated on a strength of ten clubs.
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. The clubs from Mannheim however entered the new Gauliga Baden while the teams from Trier went to the Gauliga Mittelrhein.
