The Angachak Range (Russian: хребет Ангачак; also "Большой Ангачак" —"Big Angachak") is a mountain range in the Magadan Oblast, Far Eastern Federal District, Russia.

Formerly the highest summit was thought to be Pik Aborigen, but updated measurements have found that it wasn't 2,586 metres (8,484 ft) high, but 2,286 metres (7,500 ft) high.

Thus the highest mountain of the range is 2,293 metres (7,523 ft) high Gora Snezhnaya.

In the western part lies Lake Jack London, just beneath Pik Aborigen.
