This is a list of dams on the Brahmaputra River and hydro–infrastructure in the Brahmaputra River Basin which is a key constituent of the Ganges-Brahmaputra basin of Himalayan rivers. Brahmaputra originates near Mount Kailash, flows through Tibet where it is called Yarlung Tsangpo. It enters India in Arunachal Pradesh in Eastern Himalaya, and then enters Bangladesh where it is called Jamuna (not to be mistaken with Yamuna tributary of Ganges in India). It finally flows into the Bay of Bengal where it merges with the Ganges at Sunderban Delta.

However, its tributaries, such as Padma River (name of main channel of Ganges in Ban gladesh) and Teesta River, have upstream dams in India. The proposed Ganges Barrage Project on Padma River in Bangladesh was abandoned in 2017 due to the lack of return on investment and high cost in excess of US$5 billion.
