Kazan (Russian: Каза́нь, IPA: [kɐˈzanʲ]; Tatar Cyrillic: Казан, Latin: Qazan) is the capital and largest city of the Republic of Tatarstan, Russia. With a population of 1,143,535, it is the eighth most populous city in Russia. Kazan lies at the confluence of the Volga and Kazanka Rivers in European Russia.

The Kazan Kremlin is a World Heritage Site. In 2005, the Medal "In Commemoration of the 1000th Anniversary of Kazan" was established by Russia to denote this landmark event. The multi-ethnic city is honored by UNESCO and famous for Muslims and Christians living side-by-side in peace.

In April 2009, the Russian Patent Office granted Kazan the right to brand itself as the "Third Capital" of Russia. In 2009 it was chosen as the "Sports capital of Russia" and it still is referred to as such. The city hosted the 2013 Summer Universiade and will host the 2015 World Aquatics Championships, and 2018 FIFA World Cup.
