The Principality of Novgorod-Seversk or Novhorod-Siversk was a medieval Rus' principality centered on the town now called Novhorod-Siverskyi.{{sfn|Katchanovski|Kohut|Nesebio|Yurkevich|2013|p=11–12}} The principality emerged after the central power of Kievan Rus' declined in the late 11th century, and Sviatoslav Olgovich managed to establish a local dynasty, the Olgovichi, as a branch of the Rurikid house.{{sfn|Katchanovski|Kohut|Nesebio|Yurkevich|2013|p=510–511}} Novgorod-Seversk was originally a subdivision of the Principality of Chernigov,{{sfn|Martin|2007|p=146}} and would go on to include territories that were earlier part of Chernigov and the Principality of Pereyaslavl.{{sfn|Martin|2007|p=299}}

In 1185, a large Rus' campaign against the Cumans (Polovtsy) ended in defeat for Prince Igor of Novgorod-Seversk, famously recorded in The Tale of Igor's Campaign.{{sfn|Katchanovski|Kohut|Nesebio|Yurkevich|2013|p=117}}{{sfn|Martin|2007|p=146}} After the 1205 death of Roman the Great, the first prince of Galicia–Volhynia, the three sons of Igor seized power in Halych and reigned between 1206 and 1212.{{sfn|Katchanovski|Kohut|Nesebio|Yurkevich|2013|p=197}} The principality was taken by the principality of Briansk after the Mongol invasions, and then by the Lithuanians when the power of the Golden Horde began to decline.{{cn|date=February 2023}}

In the fifteenth century the principality was given to Prince Ivan of Mozhaisk when he fled from Grand Prince Vasily II of Moscow.{{sfn|Martin|2007|p=341}}
