|Taeglin in its pass by Cabed-en-Aras, by Alan Lee|
|Location||South of Ered Wethrin and Brethil|
|Description||tributary of Sirion|
In its pass by the southeast of Brethil, it descended through the Ravines of Taeglin that skirted the eaves of the Forest. Further south, the river could be forded at the Crossings of the Taeglin, near the western border of Brethil. A road ran through it from Nargothrond to Minas Tirith.
 Other versions of the legendarium
In earlier writings, the river was called Teiglin. As revealed in the The History of Middle-earth series, the rivername should actually have been spelt Taeglin ("Boundary River"). This was a relatively late change which was not adopted into the published The Silmarillion, which uses the old name, as does The Children of Húrin.
