The Radimichs (Радимичи in Russian; Радимичі in Ukrainian), were a tribe of Early East Slavs of the last few centuries of the 1st millennium, which inhabited upper east parts of the Dnieper down the Sozh River and its tributaries. The name probably derives from the name of the forefather of the tribe - Radim.

The lands of the Radimichs were conveniently connected with the central regions of the Kievan Rus by waterways. In 11th and 12th century, the Radimichs had a few known cities: Homiy (today's Homel) and Chichers'k on the Sozh, Vschizh on the Desna River, Vorob'yin, Ropeisk, Starodub and others. Seven-beam temporal jewelry made of bronze or silver represent a specific ethnic trait of the Radimichs of the 9th - 11th century.

There is little information on the Radimichs. Historians know that in the middle of the 9th century they were paying tribute to the Khazars. In 885, the Radimichs were conquered by Prince Oleg and became part of Kyivan Rus. In 907, the Radimichs are mentioned as a part of Oleg's army in his military campaign against Czargrad. In 984, the Radimichs tried to break away from the Kievan Rus, but were defeated on the Pischan River by Vladimir the Great's commander Volchiy Khvost (Wolf's Tail). Since then, there had been no mentioning of the tribe in the chronicles. They continued living on their land, gradually assimilating with neighboring tribes and peoples and forming the Belarusian nationality. Subsequently, the lands of the Radimichs became a part of the Chernihiv and Smolensk principalities.

The Radimichs were last mentioned in a chronicle in 1169.
