The Morgulduin as it appears in The Lord of the Rings: The Return of the King

Morgulduin was a river of Ithilien, which began in the Ephel Dúath and flowed through the Morgul Vale, under the ghastly bridge that led into Minas Morgul[1], and eventually into the Anduin.[2] Because it originated in the Morgul Vale, it was icy-cold and its waters were polluted and not safe to drink from.[1] According to The Atlas of Middle-earth, the river was less than twenty-five miles in length.[2]

In the year TA 3019, Faramir warned Frodo and Sam not to drink from it, as the water was tainted and would harm whoever imbibed it.[3]

Portrayal in adaptations

The Morgulduin appears, though it is not named, in Peter Jackson's The Lord of the Rings: The Return of the King as a wide, polluted river adjacent to Minas Morgul.


Morgulduin was a Sindarin word that meant 'Black-magic River'.[4] It is unknown if its prior name was Ithilduin or if the name reverted during the Fourth Age.
