In Māori tradition, Ngātoro-i-rangi (Ngātoro) is the name of a tohunga (priest) prominent during the settling of New Zealand (Aotearoa) by the Māori people, who came from the traditional homeland Hawaiki on the Arawa canoe. He is the ancestor of Ngāti Tūwharetoa and his travels around Lake Taupō and up onto the Volcanic Plateau are the basis of Ngāti Tūwharetoa's claim to those regions.

Māori mythology and Māori traditions are two major categories into which the remote oral history of New Zealand's Māori may be divided. Māori myths concern tales of supernatural events relating to the origins of what was the observable world for the pre-European Māori, often involving gods and demigods. Māori tradition concerns more folkloric legends often involving historical or semi-historical forebears. Both categories merge in whakapapa to explain the overall origin of the Māori and their connections to the world which they lived in.
