The Volga Finns are a historical group of peoples living in the vicinity of the Volga, who speak Uralic languages. Their modern representatives are the Mari people, the Erzya and the Moksha Mordvins, as well as speakers of the extinct Merya, Muromian and Meshchera languages. The Permians are sometimes also grouped as Volga Finns.

The Volga is the longest river in Europe. 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 m3/s (280,000 cu ft/s) and 8,500 m3/s (300,000 cu ft/s) – 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.
