Argeş is a river of Southern Romania. It starts at the junction of headwaters Buda and Capra in the Făgăraş Mountains, in the Southern Carpathians and flows into the Danube at Olteniţa.
The main city on the Argeş is Piteşti. Upstream, it is retained by the Vidraru Dam, which has created Lake Vidraru.
The river is believed to be the same as Ὀρδησσός Ordessus, a name mentioned by Ancient Greek historian Herodotus. The etymology of Argeş is not clear. Traditionally, it was considered that it's derived from the ancient name, through a reconstructed term, *Argessis. The capital of Dacian leader Burebista was named Argedava, but it appears that it has no link with the name for the river.
An alternate etymology derives the name of the river from a Pecheneg word, transliterated into Romanian as argiş (meaning "higher ground"). The earliest recorded variants of the name, referring to the city of Curtea de Argeş (lit. "The Court on the Argeş"), also suggest a derivation from this word: Argyas (1369), Argies (1379), Arghiş (1427), the river probably taking the name of the city.
The following cities are situated along the river Argeş, from source to mouth: Curtea de Argeş, Piteşti and Olteniţa.
Argeş has as major tributaries: Buda, Capra, Dâmboviţa, Neajlov and Râul Doamnei.
