Waikato District is a territorial authority of New Zealand, in the northern part of Waikato Region, North Island. Waikato District is administered by the Waikato District Council, with headquarters in Ngaruawahia.
The district is centred to the north and west of the city of Hamilton, and takes in much of the northern Waikato Plains and also the Hakarimata Range. The north of the district contains swampy floodplain of the Waikato River and several small lakes, of which the largest is Lake Waikare.
Other than Ngaruawahia, the main population centres are Huntly, Raglan, and Te Kauwhata. The main industries in the district are dairy farming, forestry, and coal mining. There is a major coal-fired power station at Huntly. Te Kauwhata is at the centre of a major wine region.
At the 2006 census the district had a population of 43,959. Of these, 6834 lived in Huntly, 5106 in Ngaruawahia, 2637 in Raglan, and 1294 in Te Kauwhata. In 2010, the district acquired part of the adjacent Franklin District, which was dissolved as part of the creation of the Auckland Council.
