The Roslavl–Novozybkov offensive (Russian: Рославльско-Новозыбковская наступательная операция, lit. 'Roslavl–Novozybkov offensive operation') was an offensive conducted by the Red Army's Bryansk Front against the German 2nd Panzer Group and 2nd Army in Bryansk Oblast and parts of Sumy Oblast on the Eastern Front of World War II between 30 August and 12 September 1941, part of the Battle of Smolensk in Soviet historiography.

The offensive was an attempt by Andrey Yeryomenko's Bryansk Front to destroy Heinz Guderian's 2nd Panzer Group after it turned south towards Kiev. The offensive failed as a result of armor dispersion and poor intelligence, and the 2nd Panzer Group inflicted heavy casualties on the front's forces, significantly weakening it in advance of Operation Typhoon, which began three weeks later. The German troops continued their advance southwards, resulting in the Kiev encirclement battle.
