The Landesbank der Rheinprovinz or Rheinische Landesbank was a German provincial public bank or Landesbank, whose origins go back to the Rheinische Provinzial-Hülfskasse established 1854 in the Rhine Province of Prussia. Following uncontrolled expansion in the 1920s, it collapsed in 1931, shortly after Austria's Creditanstalt and before Danatbank, thus contributing materially to the European banking crisis of 1931.
