The Nan Ungol, or "Valley of Spiders", was a valley in the southwest corner of Mordor, against the vertex of the Ered Lithui and the Ephel Duath where many of Ungoliant's brood (Giant Spiders) lived.

It is only shown on a map of Mordor created for the cinematic lore of the Lord of the Rings films.
