Tiningnertok (Danish: Apostelen Tommelfinger, meaning 'Thumb of the Apostle') is a mountain in King Frederick VI Coast, Kujalleq municipality, southern Greenland.

[4][5] Akuliarusersuaq is another massive peak rising barely 3 km to the southeast at 60°34′13″N 43°44′4″W / 60.57028°N 43.73444°W / 60.57028; -43.73444 to a height of 1,534.67 m (5,035.0 ft).

In 1971 members of the French Club Alpin of Paris reached the base of the Apostelen Tommelfinger by helicopter, but had to desist following a number of accidents and other problems.

Two years later, in 1973, an Italian group of mountaineers also experienced failure while trying to climb this remote peak.

[7] Finally the 1976 expedition led by Frenchman Sylvain Jouty succeeded in climbing Tiningnertok.
