|Description||Tributary to the Anduin|
Greylin was a river of the far north of Middle-earth.
The Greylin rose in the western Grey Mountains and flowed south-westward to meet the Langwell and together they formed the source of the Great River, Anduin.
Between the two rivers was the Éothéod built Framsburg, their capital.
The second element of the name derives from Old English hlynn or "torrent", although its literal meaning was probably "the noisy one".
