Menmecho Lake is a mountain lake located in Gangtok district in the Indian state of Sikkim.

It lies on the way to the Jelep Pass and is situated 20 kilometres (12 mi) ahead of the Lake Tsomgo.

The waters of the lake are sourced by melting snow in summer, and the monsoon in the wet season.

The lake is noted for its trout, and has a large fish farm nearby with a guesthouse.
