Euastacus guruhgi is a species of freshwater crayfish found in the Australian state of New South Wales.

It has an estimated extent of occurrence of 80 square kilometres (31 sq mi) and an area of occupancy of 7.5 square kilometres (2.9 sq mi) where it occurs fragmentedly.

E. guruhgi also faces the consequences of global warming; as a restricted range species, it is dependent on cool headwater streams and a slight increase in the temperature of the water could rapidly eradicate the species.

[1] There are no specific conservation measures for this species in place but the distribution range of the E. guruhgi falls within the Mount Warning and Wollumbin national parks.

In New South Wales, there is a minimum recreational size limit of 90 mm orbital carpace length for any spiny crayfish.
