The Trent River is a river of the West Coast Region of New Zealand's South Island. It flows east from its source in the Kaimata Range northeast of Otira, turning north to reach the valley of the Ahaura River via the Tà «taekurë River.
The Trent River is braided and flows through beech forest. It can be kayaked, except during summer droughts.
There are two 4-bed backcountry huts in the Trent valley, the Top- and Mid-Trent Huts. Elizabeth Hut on the Haupiri River can be reached via the Trent valley in about 9 hours from Tutaekuri Hut, via the Trent Saddle, on the Elizabeth Hut Route.
