The Rhine Province (Rheinprovinz in German) was a province of the Kingdom of Prussia and the Free State of Prussia from 1822 to 1946. It was created from the provinces of the Lower Rhine and Jülich-Cleves-Berg. Its capital was Koblenz and in 1939 it had 8.0 million inhabitants.

In 1920, the Saar was separated from the Rhine Province and administered by the League of Nations until a plebiscite in 1935, when the region was returned to Germany. At the same time, in 1920, the districts of Eupen and Malmedy were transferred to Belgium (see German-Speaking Community of Belgium). In 1946, the Rhine Province was divided up between the newly-founded states of North Rhine-Westphalia and Rhineland-Palatinate.
