Zwiesel Mountain (German: Zwieselberg) is a large complex mountain which is highly dissected, rising to 2,970 m and forming the north portion of Pieck Range in the Petermann Ranges of Queen Maud Land. It was discovered and given the descriptive name "Zwiesel-Berg" (forked mountain) by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher.
