The Volga (Russian: Волга, pronounced [ˈvolɡə] ) is the longest river in Europe and the longest endorheic basin river in the world. Situated in Russia, it flows through Central Russia to Southern Russia and into the Caspian Sea. The Volga has a length of 3,531 km (2,194 mi), and a catchment area of 1,360,000 km2 (530,000 sq mi). It is also Europe's largest river in terms of average discharge at delta – between 8,000 and 8,500 cubic metres (280,000 and 300,000 ft3) per second – and of drainage basin. It is widely regarded as the national river of Russia. The hypothetical old Russian state, the Rus' Khaganate, arose along the Volga c. 830 AD. Historically, the river served as an important meeting place of various Eurasian civilizations.

The river flows in Russia through forests, forest steppes and steppes. Five of the ten largest cities of Russia, including the nation's capital, Moscow, are located in the Volga's drainage basin. Because the Volga drains into the Caspian Sea, which is an endorheic body of water, the Volga does not naturally connect to any of the world's oceans.

Some of the largest reservoirs in the world are located along the Volga River. The river has a symbolic meaning in Russian culture – Russian literature and folklore often refer to it as Волга-матушка Volga-Matushka (Mother Volga).

Name

The Russian hydronym Volga (Волга) derives from Proto-Slavic *vòlga 'wetness, moisture', which is preserved in many Slavic languages, vlaga (влага) 'moisture', Bulgarian vlaga (влага) 'moisture', Czech vláha 'dampness', Serbo-Croatian: vlaga (влага) 'moisture', Slovene vlaga 'moisture', Polish wilgoć 'moisture' and Macedonian vlaga (влага) 'moisture', among others.

The Scythian name for the Volga was Rahā, literally meaning 'wetness'. This is related to the Avestan name for a mythical stream, Raŋhā (𐬭𐬀𐬢𐬵𐬁), which means "wet" or "moisture", and was derived from Proto-Indo-European *h₁res- or *h₁ers-). This name can be compared to several Indo-Iranic terms, such as:
