Wādī Ḥalfā () is a city in the Northern state of Sudan on the shores of "Lake Nubia" (the Sudanese section of Lake Nasser). It is the terminus of a rail line from Khartoum and the point where goods are transferred from rail to ferries going down the lake. As of 2007, the city had a population of 15,725. The town is located amidst numerous ancient Nubian antiquities and was the focus of much archaeological work by teams seeking to save artifacts from the flooding caused by the completion of the Aswan Dam.
