Tauriel is a fictional character from Peter Jackson's three-part feature movie adaptation of J.R.R. Tolkien's "The Hobbit". The character does not appear in the original book by writer J.R.R. Tolkien, but was created by Peter Jackson and Fran Walsh for two of the movies. Tauriel is a Woodland Elf, and is the leader of the Elven guard. Her name means "forest daughter" in the Elvish language. She is played by actress Evangeline Lilly, who appeared as Kate Austen on the TV show "Lost".
