Puncak Trikora (literally "Peak [[Operation People's Tri-Commando") is a 4,730 or 4,750-metre-high (15,584 ft) mountain in the Highland Papua province of Indonesia on New Guinea.

Behind Puncak Jaya (Carstensz Pyramid) at 4,884 m (16,024 ft), it is either the second or third highest mountain on the island of New Guinea and the Australasian continent.

As such it appears on some Seven Second Summits lists, although SRTM-data support that Puncak Mandala (Juliana Peak) in the Jayawijaya (Orange) Range is higher with 4,760 m (15,617 ft).

The three commands were: to defeat the formation of an independent state of West Papua, raise the Indonesian flag in that country, and be ready for mobilization at any time.

A group of nine, including Lorentz and Jan Willem van Nouhuys, were the first to reach the eternal snow of New Guinea at a height of 4,460 m (14,633 ft) on November 8, 1909.

It was led by Alphons Franssen Herderschee, an officer of the Royal Netherlands East Indies Army, and it aimed to research the soils, flora, and fauna of the region that lay above 2,300 metres.

Other expedition members were the zoologist Gerard Martinus Versteeg, the botanist August Adriaan Pulle, the geologist Paul François Hubrecht, and J.B. Sitanala, an Indonesian GP.

Kremer, who was a surveyor the previous year, retraced the route, and via the upper Baliem Valley and Lake Habbema reached the summit on 4 December 1921.
