Oooof! "Urban Fantasy" is not generally separated by the publishers and marketing these days, but it's a pretty broad genre, with writers as diverse as Kuttner and Moore, Ellison, Rod Serling, China Mieville, Charles Beaumont, Michael Moorcock, and many, many others having contributed to it. It isn't as tradition-bound as what most people think of as Fantasy, which is more closely allied to High Fantasy or Sword-and-Sorcery fantasy. Serling's "Twilight Zone" scripts are a good example of one type of urban fantasy; several of Richard Matheson's stories are another. Quite a lot of Ellison would fit, and several stories of Moorcock. Fritz Leiber also wrote some, such as "Smoke Ghost" and "The Dead Man". Recent urban fantasy tends to be more gritty, more cynical (usually), and is certainly darker than most of what people take fantasy to be. Usually no struggle between Good and Evil, but people in an urban setting faced with some slightly askew, fantastic intrusion into their everyday lives, that questions their entire view of reality. Much more driven by character than by quest or battle. It frequently crosses over into "urban sf", as it sometimes pushes the story into the very near future, but it is actually fantasy set in a world very close to everyday reality... and is more difficult because it requires absolute verisimilitude with the characters, given the slight touch of the unreal. The characters cannot simply accept this intrusion, as it violates "natural law". A good short example would be Shirley Jackson's story, "The Demon Lover".
