In J. R. R. Tolkien’s fictional universe of Middle-earth, the Old Forest was a daunting and ancient woodland just beyond the eastern borders of the Shire. Its first and main appearance in print was in the chapter of the 1954 The Fellowship of the Ring titled "The Old Forest". The hobbits of the Shire found the forest hostile and dangerous; the nearest, the Bucklanders, planted a great hedge to border the forest and cleared a strip of land next to it. A malign tree-spirit, Old Man Willow, grew beside the River Withywindle in the centre of the forest, controlling most of it.

The Shire is a region of J. R. R. Tolkien's fictional Middle-earth, described in The Lord of the Rings and other works. The Shire is an inland area settled exclusively by hobbits, the Shire-folk, largely sheltered from the goings-on in the rest of Middle-earth. It is in the northwest of the continent, in the region of Eriador and the Kingdom of Arnor.

The name "Bree" was inspired by the name of the village of Brill, Buckinghamshire; it contains the Celtic Breʒ and the Old English hyll, both meaning "hill".
The Bell Inn in Moreton-in-Marsh may have inspired Tolkien to create The Prancing Pony inn at Bree.
