The Golensizi were a tribe of West Slavs, specifically of the Lechitic tribes, living in the Early Middle Ages and inhabiting southern territories of what was later known as Upper Silesia, on the upper Oder River.
The area was settled by Slavs after it was abandoned by the Germanic tribes between the 5th and 6th century. Later the organised tribe of Golensizi according to Bavarian Geographer had 5 civitates. Among them most notable were located in Lubomia, Chotěbuz and Hradec nad Moravicí which was in 1155 mentioned as Gradice Golenzicezke.
