The Tolkien Gateway is a fan wiki that documents all the characters, places, objects, and events in J. R. R. Tolkien's fantasy world of Middle-earth, with citations to Tolkien's texts.

It provides some coverage of related non-Tolkien items such as films, actors, games, music, images, and scholarly books.

[6] The site is described in Stuart D. Lee's 2014 scholarly handbook A Companion to J. R. R. Tolkien as "the main source to start a review of the plethora of Tolkien-based online materials.

"[7] It is referenced in scholarly works such as VII,[8] Journal of Tolkien Research,[9] and Social Science Computer Review.

[11] Tolkien Gateway is one of four websites described as "essential"[3] in A Companion to J. R. R.
