The Waikato Region is a local government region of the upper North Island of New Zealand. It covers the Waikato, Hauraki, Coromandel Peninsula, the northern King Country, much of the Taupo District, and parts of Rotorua District. It is governed by the Waikato Regional Council.
To the west, the region is bounded by the Tasman Sea. The coastal region is largely rough hill country, known locally as the Hakarimata Range, though it is more gently undulating in the north, closer to the mouth of the Waikato River. The coast is punctured by three large natural harbours: Raglan Harbour, Aotea Harbour, and Kawhia Harbour. The area around Raglan is noted for its volcanic black sand beaches, and also for its fine surfing conditions at Manu Bay and Ruapuke beach.
To the east of the coastal hills lies the broad floodplain of the Waikato River.
