Terningen Peak is a small rock peak marking the summit of Terningskarvet Mountain in the Gjelsvik Mountains, Queen Maud Land. It was photographed from the air by the Third German Antarctic Expedition (1938-1939), led by Capt. Alfred Ritscher. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949-1952), led by John Schjelderup Giæver, and later by air photos by the Norwegian expedition (1958-59) and named Terningen (the die).
