This is a list of units of administrative division of the Republic of Tatarstan, a federal subject of Russia.

In 1922, Yelabuga with environs was transferred to the Tatar ASSR from Vyatka Governorate.

Initially, the territory of the ASSR was divided into ten kantons - Sviyazhsk, Tetyushi, Buinsk, Spassk, Chistopol, Menzelinsk, Bugulma, Arsk, Laishevo, and Mamadysh.

All kantons had roughly the same borders and the territory as the uyezds which preceded them, and preserved the division into volosts.

In the 1930s, kantons were finally abolished and replaced with forty-five districts (raions).
