Patumāhoe is a small town of Auckland, New Zealand. It is in the Franklin Ward of Auckland Council.

The name comes from the Māori patu māhoe, meaning "to strike or kill with a patu (club) made of wood from the māhoe plant".

In October, 1860 a Māori by the name of Eriata was found shot dead. Wiremu Tamehana prevented Māori from seeking revenge and the Anglican missionaries George Augustus Selwyn, Arthur Purchas, and Robert Maunsell managed to de-escalate tensions. Eriata's death was accidental and self-inflicted, although this was not known until after tensions has been de-escalated.
