Nethermost Pike is a mountain in the English Lake District. By Wainwright's definition it is the ninth highest mountain in the Lake District. It lies one kilometre south of its bigger and more famous neighbour Helvellyn, and is usually climbed along with it.
The western slopes going down to Thirlmere which are crossed by the Wythburn path to Helvellyn, are steep, grassy and uninteresting, but on the east side is a wilderness of steep crags, combes and streams falling into Grisedale .
