The Drevlians (, ) were a tribe of Early East Slavs between the 6th and the 10th century, which inhabited the territories of Polesia and Right-bank Ukraine, west of the eastern Polans and along the lower reaches of the rivers Teteriv, Uzh, Ubort, and Stviga.
A occidente i territori dei Drevljani raggiungevano il fiume Sluč abitato dai Volyniany e dai Bužans (da cui prese il nome il fiume Bug).
