Lothlórien was a forest located in Middle-earth, next to the lower Misty Mountains. It was first settled by Nandorin elves, but later enriched by Ñoldor and Sindar, under Celeborn of Doriath and Galadriel, daughter of Finarfin.

Lórien was located on the River Celebrant, southeast of Khazad-dûm, and was the only place where the golden Mallorn tree grew in Middle-earth. The chief city of Lothlórien was Caras Galadhon.
