Ketetahi Hot Springs is a geothermal feature on the northern descent of the Tongariro Alpine Crossing in Tongariro National Park, New Zealand.

Visible from the track near Ketetahi Hut, the springs are marked by plumes of steam and mineral-streaked rocks stained by the effects of hot water on the andesitic geology. The largest fumarole discharges superheated steam reaching around 138°C.

The springs sit on a small area of private Māori land, and while hikers pass close by on the main track, there is no right of access to the springs themselves.

They lie on the descent from Blue Lake (Te Wai-whakaata-o-te-Rangihiroa), with views opening toward Lake Rotoaira as the trail continues down to the Ketetahi car park.
