The 3rd Infantry Division was an infantry division of the German Army that fought in World War II. The division was established under the cover name Wehrgauleitung Frankfurt in 1934 by expanding the 3rd Division of the Reichswehr. It was redesignated Kommandant von Frankfurt shortly afterward, and took on its bona fide name when the formation of the Wehrmacht was announced in October 1935. In March 1939 the division took part in the invasion and occupation of Czechoslovakia.
