Mount Tūtoko is the highest peak in Fiordland National Park, in southwest New Zealand.

It lies between the Hollyford Valley and Milford Sound, 15 kilometres (9.3 mi) due north of the Homer Tunnel at the northern end of the Darran Mountains.

The glacier-covered mountain rises to a height of 2,723 metres (8,934 ft) and is visible from the Hollyford Track.

The first ascent of Tūtoko was by Samuel Turner and Peter Graham in 1924, climbing by way of the northwest ridge.

The mountain was named by James Hector, who visited the area in 1863, after Tūtoko, a Māori chief (rangatira) living at Martins Bay, close to the mouth of the Hollyford River, at the time.
