That depends where you draw the line. The Third Reich considered Vichy France a client state, dependent on but legally separate from itself. The north and west of France, including Normandy, fell under German military occupation after 1940 (as did the rest of the country after 1942), but that ostensibly represented wartime defense needs rather than a permanent territorial claim.

Germany did administer some French lands as part of itself during the war, all in France's northeast along the German border. There's some indication that territorial expansion would have proceeded further had the Nazis won, but most of the Third Reich's annexations took place east of Germany's prewar territory.
