The King Country (Māori: Te Rohe Pōtae or Rohe Pōtae o Maniapoto) is a region of the western North Island of New Zealand. It extends approximately from Kawhia Harbour and the town of Ōtorohanga in the north to the upper reaches of the Whanganui River in the south, and from the Hauhungaroa and Rangitoto Ranges in the east to near the Tasman Sea in the west. It comprises hill country, large parts of which are forested.

The region, albeit loosely defined, is very significant in New Zealand's history. The term "King Country" dates from the New Zealand Wars of the 1860s, when colonial forces invaded the Waikato and forces of the Māori King Movement withdrew south of what was called the aukati, or boundary, a line of pā alongside the Puniu River near Kihikihi. Land behind the aukati remained native territory, with Europeans warned they crossed it under threat of death.

Known for its rugged, rural roads and diverse landscape, the King Country has a warm climate, considered subtropical.

The King Country is not an entity in local government. It forms part of two local government regions, Waikato and Manawatū-Whanganui, and all or part of four districts: Ōtorohanga, Ruapehu, Taupō and Waitomo.

Taranaki-King Country is a parliamentary electorate for central government. The member represents an area which stretches from the outskirts of New Plymouth City to the outskirts of Hamilton City and including the King Country towns of Te Awamutu, Ōtorohanga and Te Kūiti.

The King Country (a.k.a. Western Uplands) is largely made up of rolling hill country, including the Rangitoto and Hauhungaroa Ranges. It includes extensive karst regions, producing such features as the Waitomo Caves.

The area is largely rural and sparsely settled, with no cities or large towns. The most significant townships are the rural service centres of Te Kūiti and Ōtorohanga (in the north) and Taumarunui (in the south).

Prior to European settlement, the area was occupied by various Māori iwi, especially Ngāti Maniapoto, Ngāti Tama, and Ngāti Tūwharetoa.
