Te Kooti's War is one of the New Zealand Wars, the series of conflicts fought between 1845 and 1872 between the Māori and the colonizing British settlers, often referred to as Pākehā.

This particular conflict covers most of the East Cape region and the center of the North Island of New Zealand from July 1868 until mid 1872.

It is the longest and in some ways the ugliest and most savage of all the New Zealand Wars.
