Fan Fics (Fanfic)
Fan Fics are a diverse beast. The only real "rule" is that they have to be based on existing source material. (Although in general "fan fiction" tends to refer to material written in and about trademarked properties; if the subject matter is in the Public Domain the result is not strictly speaking "fanfic".) We here at All The Tropes care about them mainly to this extent—is it worthy enough that someone, somewhere, was willing to write a reasonably good trope page for it? If yes, then this is your index - a catalog of all notable fanfics, classified by the works they're based off of.
Please don't mistake a fanfic's inclusion on this page as being some sort of vindication of it as being a piece of art. Remember that we're a wiki for all trope-based fiction, good or bad. Whether or not something is liked has nothing to do with tropes. In other words, while many of the fics listed below are considered worth a read by a number of tropers, that can still mean that the fic in question is very, very bad.
Note that since this is intended to be an index of fics with pages, a Red Link will be frowned on and given a very brief (week or two) grace period before being removed by your fellow tropers. Start the page for the fic if you think it should be in this index.
This page is for fanfiction and authors only. Other types of fan work belong on the subpages of Fan Work (Fan Film, Fan Vid, Filk Song, and so on). We're working on moving the misplaced works—help Fan Films, Fan Vids, and others get to their correct index!
