Leo Dietrich Franz Reichsfreiherr Geyr von Schweppenburg was a German general in the Wehrmacht during World War II, noted for his pioneering stance and expertise in the field of armoured warfare. He commanded the 5th Panzer Army during the Invasion of Normandy, and later served as Inspector General of Armoured Troops. After the war he was involved in the development of the newly built German Army (Bundeswehr).

5th Panzer Army was the name of two different German armoured formations during World War II. The first of these was formed in 1942, during the North African campaign and surrendered to the Allies at Tunis in 1943. The army was re-formed in France in 1944, fought in Western Europe and surrendered in the Ruhr pocket in 1945.
