The Mangatāwhiri River is a river of the Waikato region of New Zealand's North Island. It flows generally southwest from its sources in the Hunua Ranges southeast of Clevedon before flowing through a system of irrigation canals at the northern edge of the Waikato Plains close to the town of Pōkeno. It reaches the Waikato River close to the township of Mercer.
The New Zealand Ministry for Culture and Heritage gives a translation of "Tāwhiri tree stream" for Mangatāwhiri.
The upper reaches of the Mangatāwhiri are dammed to form reservoirs to store water for use by Auckland City.
