The Chuvash people (Chuvash: Чăвашсем; Russian: Чуваши) are a Turkic ethnic group, native to an area stretching from the Volga Region to Siberia. Most of them live in Republic of Chuvashia and surrounding areas, although Chuvash communities may be found throughout all Russia.

There is no universally accepted etymology of the word Chuvash. However, there are two main theories that try to explain it.

According to one theory, "Chuvash" is a Shaz-Turkic adaptation of Lir-Turkic Suvar, an ethnonym of people that are widely considered to be the ancestors of modern Chuvashes. Compare Lir-Turkic Chuvash: huran to Shaz-Turkic Tatar: qazan (cauldron).

Another theory suggests that the word "Chuvash" may be derived from Common Turkic jăvaš ("friendly", "peaceful") as opposed to şarmăs ("warlike").

There are rival schools of thought on the origin of Chuvash people. One is that they originated from a mixing between the Turkic Suar and Sabir tribes of Volga Bulgaria with local Mari tribes and also the Finno-Ugrian population of the Volga Basin. Another is that the Chuvash are a remainder of the pre-Volga Bulgar population of the Volga region, merged with Scythians, Volga Bulgars and Mari.

The Turkic peoples are a collection of ethnic groups that live in northern, central and western Asia, northwestern China and parts of eastern Europe. They speak languages belonging to the Turkic language family. They share, to varying degrees, certain cultural traits and historical backgrounds. The term Turkic represents a broad ethno-linguistic group of people including existing societies such as the Turkish, Azerbaijani, Chuvashes, Kazakhs, Tatars, Kyrgyzs, Turkmens, Uyghurs, Uzbeks, Bashkirs, Qashqai, Gagauzs, Yakuts, Crimean Karaites, Krymchaks, Karakalpaks, Karachays, Nogais and as well as past civilizations such as the Göktürks, Kumans, Kipchaks, Avars, Bulgars, Turgeshes, Khazars, Seljuk Turks, Ottoman Turks, Mamluks, Timurids and possibly Huns and the Xiongnu.

The distribution of people of Turkic cultural background ranges from Siberia, across Central Asia, to Eastern Europe. As of 2011^[update] the largest groups of Turkic people live throughout Central Asia—Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan, and Azerbaijan, in addition to Turkey and Iran. Additionally, Turkic people are found within Crimea, East Turkistan region of western China, northern Iraq, Pakistan, Israel, Russia, Afghanistan, and the Balkans: Moldova, Bulgaria, Romania, and former Yugoslavia. A small number of Turkic people also live in Vilnius, the capital of Lithuania. Small numbers inhabit eastern Poland and the south-eastern part of Finland. There are also considerable populations of Turkic people (originating mostly from Turkey) in Germany, United States, and Australia, largely because of migrations during the 20th century.
