Diamer-Bhasha Dam is a concrete-filled gravity dam, in the preliminary stages of construction, on the River Indus in Gilgit-Baltistan in Pakistan.

Upon completion, Diamer-Bhasha Dam would be the highest roller-compacted concrete (RCC) dam in the world.

The dam site is situated near a place called "Bhasha" in Gilgit-Baltistan's Diamer District, hence the name.

The gross capacity of the reservoir will be 8,100,000 acre feet (10 km3), with a live storage of 6,400,000 acre feet (7.9 km3).

Two underground power houses are being proposed, one on each side of the main dam having six turbines on each side with total installed capacity 4500 MW.

Upon completion, Diamer-Bhasha Dam would produce 4,500 megawatts of electricity through environmentally clean hydropower generation.

It would store an extra 8,500,000 acre feet (10.5 km3) of water for Pakistan that would be used for irrigation and drinking.

It will help extend the life of Tarbela Dam located downstream by 35 years.

It will also control flood damage by the River Indus downstream during high floods.

It will have a height of 272 meters spillway with fourteen gates each 11.5 m x 16.24 m.
