Calenhir was a river in Gondor that flowed east from the Pinnath Gelin into the Morthond. On the "working map" that J.R.R. Tolkien used while writing The Lord of the Rings the river was drawn on the map but only named in the list of the "Rivers of Gondor". This river was removed from the maps of the published Lord of the Rings and the Unfinished Tales.
