The Sherabad River, Shirabad River or Sherabad Darya (Darya meaning river) is a right tributary of the Amu Darya in south-central Tajikistan. It is about 130 kilometres (81 mi) long and drains an area of 11,000 square kilometres (4,200 sq mi). The river rises in the arid foothills of the Gissar Range and flows south through steppe before flowing through a mountain ridge to empty into the Central Asia plain near Shirabad. The river turns south and flows past Akkürgon, to flow into the Amu Darya near Shuro-obod. Because of irrigation water use, most of the water in the Sherabad no longer reaches the Amu Darya and its eventual destination in the Aral Sea. After flowing out of the mountains the remaining water in the river is usually salty so it is unsuitable for further water use. In dry years, most of the river dries up before reaching the Amu Darya.
