Kashin (Russian: Ка́шин) is a town and the administrative center of Kashinsky District in Tver Oblast, Russia, located around a rural agricultural area on the Kashinka River (Volga's tributary).

[citation needed] It was given by Grand Duke Mikhail Yaroslavich as an appanage to his son Vasily, who founded a short-lived dynasty of local princes.

Mikhail Yaroslavich's wife Anna took the veil in Kashin's nunnery, died there on October 2, 1368, and was glorified by the Russian Orthodox Church in 1650 as a holy patroness of all women who suffer the loss of relatives.

[citation needed] In 1775, Tver Viceroyalty was formed from the lands which previously belonged to Moscow and Novgorod Governorates, and Kashinsky Uyezd with the seat in Kashin was established.

The town contains thirty-six cultural heritage monuments of federal significance, including the ensemble of the Presentation Monastery and a number of churches built in the 18th and the 19th centuries.
