Sevsk (Russian: Севск) is a town and the administrative center of Sevsky District in Bryansk Oblast, Russia, located on the Sev River [ru; es] (Dnieper's basin), 142 kilometers (88 mi) from Bryansk, the administrative center of the oblast.

In the middle of the 17th century a Sev fortress was included in the system of newly created defensive guards along the south-western borders.

The convenient location contributed to the creation of a strong fortress here, which played a significant role in the history of Russia.

In the 1880s, the first railway line ran through Sevsky uyezd, but Sevsk itself was left out of it, which affected the development of industry and trade.

In the north-western part of the city in 1913, a large two-story building was erected, specially designed for the Sevsky Real School, established in 1909.

The school became one of the cultural centers of the city, where literary evenings were held, concerts were arranged, and amateur performances were staged.
