The Mingha River is a river of the Canterbury Region of New Zealand's South Island. It flows east then south from its origin on the slopes of Mt Temple, meeting the Bealey River 8 km south of Arthur's Pass. Together with Goat Pass, elevation 1071 m, and the Deception River, the Mingha valley forms a route across the Southern Alps known as the Mingha/Deception. It is used for the mountain running segment of the annual Coast to Coast race.
