List of fictional settlements

This is a list of fictional settlements, including fictional towns, villages and cities, organized by each city's medium. This list should include only well-referenced, notable examples of fictional towns, cities, settlements and villages that are integral to a work of fiction and substantively depicted therein. Fictional cities, towns and counties are arrows in the fiction writers' quivers – they lend an air of authenticity to the story, and since there are so many of them, readers find them to be a plausible addition that makes the story more realistic.
