Novozybkov (Russian: Новозы́бков; Belarusian: Навазыбкаў) is a historical town in Bryansk Oblast, Russia with a population, in 2021, of 38,680.

[citation needed] Novozybkov was a major hemp supplier in the 18th and 19th centuries, particularly for the production of ropes for the Imperial Russian Navy.

Following the Crimean War, the demand for hemp fell, and cultivation stopped altogether at the beginning of the 20th century.

The area not suitable for human habitation (more than 40 Ci/km2 (1.5 MBq/m2)) starts at 1 km west of Novozybkov city limits.

[8] As a result of the Chernobyl disaster on April 26, 1986, part of the territory of Bryansk Oblast has been contaminated with radionuclides (mainly Gordeyevsky, Klimovsky, Klintsovsky, Krasnogorsky, Surazhsky, and Novozybkovsky Districts).
