John Howe's maps of Middle-earth (available in a big box set) are pretty good, and his map of Middle-earth is definitive as far as I'm concerned.
Jonathan Roberts created a set of maps for A Song of Ice and Fire/Game of Thrones called The Lands of Ice and Fire which are excellent. I have the big map of the entire world on my wall.
There is an official map available, here's a link to it on Amazon UK

I have the map of Ankh Morpork and it's pretty interesting

Check The Discworld Mapp. Large fold-out map of the Disc that could be adapted to a tabletop.

Terry Pratchett has a whole set of maps for his Discworld books, including the entire Discworld itself and the city of Ankh-Morpork (both twice, in fact, in The Streets of Ankh-Morpork, The Compleat Ankh-Morpork, The Discworld Mapp and The Compleat Discworld Atlas).
You can buy a map of Roshar from Brandon Sanderson's website and one of Temerant from the Worldbuilders Store.
