Sumantri Peak (also spelled Soemantri or Soemantri Brodjonegoro^[1][2]) is a sharp mountain in the western Sudirman Range (Central Papua). It rises 4,870 metres (15,978 ft).

The peak is approximately 2 km northeast of Carstensz Pyramid (4,884 m), the highest mountain of Oceania. The north side of Sumantri is dominated by tremendous cliffs, part of the Noordwand (Northwall) of the Carstensz Massif, that wrap around to the eastern and western sides of the mountain. Remnants of the once mighty Northwall Firn (now separated into eastern and western parts) cling tenuously to the southern aspects of the peak. It is unlikely that this ice will last for more than the next 15 years^[when?].^[2]
