Puncak Trikora, until 1963 Wilhelmina Peak, is a 4730 or 4,750 m (15,584 ft) high mountain in the Papua province of Indonesia on New Guinea. It lies in the eastern part of the Sudirman (Nassau) Range of the Maoke Mountains. 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).
Puncak Trikora was covered by an ice cap that melted between 1936 and 1962. In 1909 the ice cap still reached as low as 4,400 m (14,436 ft).
