First level administrative division of Russia

Chuvashia (Чувашия; ), officially the Chuvash Republic — Chuvashia, is a republic of Russia located in Eastern Europe. It is the homeland of the Chuvash people, a Turkic ethnic group. Its capital is the city of Cheboksary. As of the 2010 Census, its population was 1,251,619.

The Chuvash Republic is located in the center of European Russia, in the heart of the Volga Vyatka economic region, mostly to the west of the Volga River, in the Volga Upland. It borders with the Nizhny Novgorod Oblast in the west, Mari El Republic in the north, the Republic of Tatarstan in the east and southeast, Republic of Mordovia in the southwest, and the Ulyanovsk Oblast in the south. There are over two thousand rivers in the republic—with the major ones being the Volga, the Sura, and the Tsivil—as well as four hundred lakes. Some of the Volga River valley reservoirs are in the north of the republic, and the Sura River flows towards the Volga along much of the republic's western boundary. The climate is moderately continental, with the average temperatures ranging from in January to in July. Annual precipitation varies between , but is uneven from one year to another. Natural resources include gypsum, sand, clay, sapropel deposits, phosphorite, and peat. There are oil and natural gas deposits, although their extraction has not yet been commercially pursued. Forests, mostly in the south along the Sura River, cover approximately 30% of the land.

The ancestors of the Chuvash were Bulgars and Suars, Oghur Turkic tribes residing in the Northern Caucasus in the 5th to 8th centuries. In the 7th and 8th centuries, a part of the Bulgars left for the Balkans, where, together with local South Slavs, they established the state of modern Bulgaria. Another part moved to the Middle Volga Region (see Volga Bulgaria), where the Bulgar population that did not adopt Islam formed the foundation of the Chuvash people.

Osteopetrosis affects 1 newborn out of every 20,000 to 250,000 worldwide, but the odds are much higher in the Russian region of Chuvashia (1 of every 3,500–4,000 newborns) due to genetic traits of the Chuvash people.

There are five higher educational institutions, including the Chuvash State University, the Chuvash State Pedagogical University, and the Chuvash State Agrarian University located in Cheboksary. These, together with 28 colleges and technical schools, are currently attended by approximately 45,000 students.

The Chuvash Republic is the most populous and fertile area in the middle Volga region. There are deciduous woodlands on fertile black earth. In agriculture, wheat and sugar beet, pigs and beef cattle have become more important than the rye, oats, barley and dairy cattle which are typical for the whole area. The republic is Russia's center for growing hops and is famous throughout the country for its long history of beer brewing. It is also a major center for electrical engineering, especially in the area of power transmission and control systems.

The transport network in the republic is one of the most developed in Russia. The republic's system of roads, railroads, waterways, and airports closely ties the region with others in and outside of Russia.

Only four roads in the Chuvash Republic are classified as important federal highways. The most important is Highway M 7, which runs from Nizhny Novgorod through the northern parts of the republic from Yadrinsky Nikolskoye via Malye Tyumerli, Kalmykovo, Khyrkasy, Novye Lapsary, Kugesi, Shivlinsk, Staraya Tyurlema, to Kazan in the Republic of Tatarstan. It also forms a connection via Chuvashia through the southern suburbs of Cheboksary and Novocheboksary to the Mari El Republic and the Vyatka Highway. Part of this road is classified as a motorway, the only one in the republic. From Yadrinsky Nikolskoye, the federal road P 178 runs through Yadrin, Shumerlya, Alatyr, to Surskoye in Ulyanovsk Oblast and further to Ulyanovsk. In the eastern part of Chuvashia, the federal road A 151 runs from Tsivilsk through Kanash, Komsomolskoye, Chkalovskoye, Karabay Shemursha, Shemursha to Ulyanovsk and Saratov. All other roads in Chuvashia are classified as local area roads. Automobiles, trucks, and buses are the major forms of transportation, with the republic ranking fourth in highway density in all of Russia. Cheboksary is situated on one of the main highways of the Russian Federation leading from Moscow to the industrial areas of Tatarstan, the southern Urals, and Siberia. A recently completed bridge across the Volga River in the north connects the republic to the developed Ural and Volga Federal Districts. To the south, highways connect Chuvashia with Saratov and Volgograd. Extensive public and private bus systems connect all towns within the republic with each other and with the surrounding regions. The standard speed of transportation of containers by road is per day. The average time of delivery from Cheboksary to Moscow is 1.5 days; to Saint Petersburg, 2.5 days; and to Western Europe, 10 to 15 days.

The Volga and Sura Rivers connect Chuvashia to a national and international water network. To the south, Volgograd, Rostov on Don, Astrakhan, the Caspian Sea, and Black Sea are directly reachable. To the west, the Volga River connects Cheboksary with Nizhny Novgorod, Yaroslavl, Moscow and the northern regions of Russia. By using river sea vessels, cargo transportation is possible from Chuvash river ports all the way to Saint Petersburg, Novorossiysk (on the Black Sea), Astrakhan, and ports situated on the Danube River. However, the river is frozen from December through April. Cheboksary is a frequent stop on the many boat tours of the Volga.

The international Cheboksary Airport receives both cargo and passenger aircraft of practically all types and sizes. There are regularly scheduled flights to Moscow and other destinations. Additionally, Cheboksary is about a four hour drive from Strigino International Airport, the airport primarily serving Nizhny Novgorod, which offers a greater number of flights, including connections through Aeroflot and Belavia.

Chuvash Republic, along with Mordovia, has given some of the best modern race walkers, as Vera Sokolova, Olimpiada Ivanova, Yelena Nikolayeva and Vladimir Andreyev. Additionally, the 2008 IAAF World Race Walking Cup was held in Cheboksary. Chuvash Republic is also represented by the basketball team Cheboksary Hawks, which performs in Russia Superleague 2.
