Tom Bombadil is a character in J.R.R. Tolkiens legendarium, first appearing in print in a 1934 poem called "The Adventures of Tom Bombadil". He is a mysterious being who lived for much of the history of the world, being known in the Third Age to dwell in the valley of the Withywindle. Commentators have debated Bombadils role and origins, with some stating that he is the spirit of a place, a genius loci. Tolkien himself described Tom Bombadil as "just an invention" and "not an important person – to the narrative", even if "he represents something that I feel important, though I would not be prepared to analyze the feeling precisely".

Some key features of Tom Bombadil include:

• Age and Race: Tom Bombadils exact age and race are not known, but it is said that he existed since sometime before the first Dark Lord (Melkor) rose to power. His exact race is also not known, and he remains mysterious—although with some apparent magical and spiritual abilities.

• Abilities: Tom Bombadil is said to be able to control and bend his surroundings to his own will. This includes influence over both the forest itself as well as those who live within it. He is also able to completely resist the power of the One Ring.

• Appearances: Tom Bombadil appears in "The Fellowship of the Ring" and "The Adventures of Tom Bombadil". He was not portrayed in the film adaptations of "The Lord of the Rings".

Overall, Tom Bombadil remains a mysterious and intriguing character in Tolkiens legendarium, with much debate surrounding his origins and significance to the narrative.
