The Rhine Province, also known as Rhenish Prussia or synonymous with the Rhineland, was the westernmost province of the Kingdom of Prussia and the Free State of Prussia, within the German Reich, 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 million inhabitants.

The small exclave district of Wetzlar, wedged between the grand duchy states Hesse-Nassau and Hesse-Darmstadt was also part of the Rhine Province. The principality of Birkenfeld, on the other hand, was an enclave of the Grand Duchy of Oldenburg, a separate state of the German Empire.
