The Huorns are a fictional race created by J. R. R. Tolkien in The Lord of the Rings. Huorns are creatures much Ents, although they do not appear to have been truely sentient. It is not clear if Huorns are Ents that have become tree-like, or trees that have become Entish. Perhaps both varieties exist.

Huorns are only directly mentioned in the LOTR narrative as existing in the Fangorn forest, where they are roused by Treeboard and help the Rohirrim win an important battle at the Hornburg. It is possible that the trees of the Old Forest, especially Old Man Willow. were Huorns as well.
