The Reting Tsangpo (Chinese: 热振河; pinyin: rè zhèn hé) is a river in the Tibet Autonomous Region of China.

The Reting Tsangpo originates in the Chenthangula Mountains at an elevation of about 5,500 metres (18,000 ft), and flows southwest.

[1] The river is said to excellent for kayaking and white water rafting, although as of 2015 it had been visited by few tourists interested in these sports.

[5] The Reting Tsangpo flows through the east central region of Tibet's Eocene block.

The Tsangpo Suture is to the south and the northwest extension of the Ailao Shan Fault is to the north.

[1] Large faults developed over the last fifty million years, and these dictate the direction in which the rivers of the region flow.
