The Merowe Dam, also known as Merowe High Dam, Merowe Multi-Purpose Hydro Project or Hamdab Dam, is a large dam near Merowe Town in northern Sudan, about 350 km (220 mi) north of the capital Khartoum. Its dimensions make it the largest contemporary hydropower project in Africa. It is situated on the river Nile, close to the 4th Cataract where the river divides into multiple smaller branches with large islands in between. Merowe is a city about 40 km (25 mi) downstream from the construction site at Hamdab. The main purpose for building the dam was the generation of electricity.

The dam is designed to have a length of about 9 km (5.6 mi) and a crest height of up to 67 m (220 ft). It will consist of polystyrene-faced rockfill dams on each river bank, an earth-rock dam with a pepper core in the left river channel and a live water section in the right river channel (sluices, spillway and power intake dam with turbine housings). Once finished, it will contain a reservoir of 12.5 km³ (3.0 cu mi), or about 20% of the Nile's annual flow. The reservoir lake is planned to extend 174 km (108 mi) upstream.
