Sosnytsia (Ukrainian: Сocниця) is a rural settlement in Koriukivka Raion (district) of Chernihiv Oblast (province) in north-central Ukraine.

The name was first recorded in the Hypatian Codex, where a chronicle from the year 1234 mentions that Danylo of Halych, while assisting the Kievan Grand Princes in their battle with Michael of Chernigov, had liberated several towns, including Sosnytsia.

Settlements from the age of Kievan Rus' in the area have yielded impressive examples of skilled metalwork, in addition to evidence of a developed agricultural society, capable of producing its own livestock.

The area was resettled in 1370 during the reign of the Grand Duchy of Lithuania, and after a military conflict, it was ceded to Muscovite Russia in 1503.

This was shortly reversed in the aftermath of the Treaty of Pereyaslav, when Russia grew to encompass its eventual empire.
