Paranephrops planifrons or northern koura is a species of southern crawfish in the family Parastacidae.

[2][1] P. planifrons is one of two indigenous species of freshwater crayfish found in New Zealand.

Both species of Paranephrops are important resources to the indigenous Māori, particularly in the Te Arawa and Lake Taupō regions.

[3] The International Union for Conservation of Nature's conservation status of P. planifrons is "LC", least concern, with no immediate threat to the species' survival.

[1] Paranephrops planifrons is smaller than the southern kōura, Paranephrops zealandicus, and has front claws that are less hairy.
