The Waihora River is a river of the Gisborne Region of New Zealand's North Island.

It flows generally west from its sources in rough hill country southwest of Tolaga Bay to reach the Waipaoa River at Te Karaka.

The New Zealand Ministry for Culture and Heritage gives a translation of "spread-out waters" for Waihora.
