Galadhrim means 'Tree-people'.

The Galadhrim were the Silvan Elves of Lothlórien. The main settlement of the Galadhrim was at Caras Galadhon, the 'City of Trees'.

The elves of Lothlórien were called the Galadhrim because of their age-old practice of dwelling in and amongst the Mallorn trees of their land.

The Galadhrim were led, during the Third Age, by Celeborn and Galadriel.
