Wessel Oskar Karl Johann Freiherr Freytag von Loringhoven, was a Baltic German colonel in the High Command of the German Armed Forces (OKW) and a member of the German Resistance (Widerstand) against Adolf Hitler. Loringhoven was a friend of Claus von Stauffenberg, who was the leader of the 20 July Plot to assassinate Hitler in 1944.

The Oberkommando der Wehrmacht was the supreme military command and control office of Nazi Germany during World War II. Created in 1938, the OKW replaced the Reich Ministry of War and had oversight over the individual high commands of the country's armed forces: the army, navy, and air force.
