The 1940 Field Marshal Ceremony refers to a promotion ceremony held at the Kroll Opera House in Berlin in which Adolf Hitler promoted twelve generals to the rank of Generalfeldmarschall ("field marshal") on 19 July 1940. It was the first occasion in World War II that Hitler appointed field marshals due to military achievements.

The prestigious rank of field marshal had been banned after World War I. As part of German re-armament, the rank was revived. Hitler promoted twelve selected generals to field marshal during the ceremony in Berlin for their role in the swift victory in the Battle of France and to raise morale. The ceremony highlighted the power and prestige of the Wehrmacht; France was considered to have had the strongest army in Europe, yet had been humiliatingly defeated in just six weeks. The ceremony was the first time Hitler appointed field marshals due to military achievements and was celebrated like no other promotion ceremony of the war.

During the same ceremony, Göring, already Generalfeldmarschall since 1938, was promoted to the rank, newly-created especially for him, of Reichsmarschall.
