Khorinsk (Russian: Хо́ринск, Buryat: Хори, Khori) is a rural locality (a selo) and the administrative center of Khorinsky District of the Republic of Buryatia, Russia.

[8] Khorinsk was formed by the merger of two villages: Duma and Bazar.

In the village bazaar lived Yasak peasants and they held trade fairs.

After the abolition of the Steppe Duma, the village became known as Nikolskoye.

In 1917, Nikolskoye was renamed Dodo-Anninskoe.
