Treebeard, or Fangorn in Sindarin, is a tree-giant character in J. R. R. Tolkien's "The Lord of the Rings". He is an Ent and is said by Gandalf to be "the oldest living thing that still walks beneath the Sun upon this Middle-earth." He lives in the ancient Forest of Fangorn, to which he has given his name. It lies at the southern end of the Misty Mountains. He is described as being about 14 feet (4.5 m) in height, and in appearance similar to a beech or an oak.
