The Terek River (Russian: Те́рек, IPA: [ˈtʲerʲɪk]; Karachay-Balkar: Терк, Terk; Georgian: თერგი, Tergi; Ossetian: Терк, Terk; Kumyk: Терек-сув, Terek-suv; Chechen: Теркa, Terka), a major river in the Northern Caucasus, flows through Georgia and Russia into the Caspian Sea. It rises in Georgia near the juncture of the Greater Caucasus Mountain Range and the Khokh Range, to the southwest of Mount Kazbek, winding north in a white torrent between the town of Stepantsminda and the village of Gergeti toward the Russian region North Ossetia and the city of Vladikavkaz. It turns east to flow through Chechnya and Dagestan before dividing into two branches which empty into the Caspian Sea. Below the city of Kizlyar it forms a swampy river delta around 100 kilometres (62 mi) wide. The river is a key natural asset in the region, providing irrigation and hydroelectric power in its upper reaches.
The Terek drains most of the northeast Caucasus east into the Caspian just as its sister, the Kuban River, drains the northwest Caucasus west into the Black Sea. Its major tributaries are the following. In the west a fan of rivers flows east and northeast into the Terek. These are the east-flowing Malka River, the Baksan River, the Chergem River and the Cherek River with its two branches. These three join the Malka just before it reaches the Terek. The Liashen, Urukh River, Duradur and Duradon flow northeast, the Ardon River and its branch, the Fiagdon River flow north and the Gizeldon River drains the north slope of Mount Kazbek and reaches the Ardon near its mouth. Then there is the north-flowing part of the Terek with the Darial Pass. The great northwest bend of the Terek is cut off by the northeast-flowing Sunzha River which catches most of the north-flowing rivers. These are the north-flowing upper Sunzha, the Assa River, the Argun and Khukhulau. East of these are the Aksay River and the Aktash River which formerly dried up in the lowlands between the Sulak and the Terek. In the east the Sulak River drains most of interior Dagestan and turns east to the Caspian before it reaches the Terek.
The Terek river was the site of the final defeat of the army of Hulagu, khan of the Ilkhanate, at the hands of the army of Berke, khan of the Golden Horde, led by Berke's nephew, Nogai Khan, in the first civil war of the Mongol Empire, the Berke–Hulagu war of 1262. Also on the river Timur defeated Tokhtamysh in 1395.
During World War II, German forces at the end of August 1942 reached the Terek near Mozdok – the farthest extent of German conquests in the Soviet Union – but aside from a small bridgehead were unable to forge further toward the oil fields of Baku, Hitler's objective.
