The Brandywine was a river of Middle-earth located in both the land of the Shire and northern Eriador. Flowing out of Lake Evendim in northern Eriador, the river flowed eastward for about 60 miles before turning generally southward; and afterwards for about another 120 miles flowed through the easternmost reaches of the Shire, forming the Shire's eastern border and separating most of Buckland, except for the parts that lay between it, and the Old Forest from the Shire. Its only major crossings in the Shire were the Brandywine Bridge (originally Bridge of Stonebows) on the East Road and the Bucklebury Ferry.
