Archived below are several maps detailing the locations within the Galaxy used in Star Trek. This archive will continue to grow as the discovery of new worlds, life, and civilizations come to light. 

Warning: The detailed Galactic Map, Milky Way Galaxy, and Sector maps are quite large. The Galactic Map comes courtesy of Juan Carlos Holmes and the USS Icarus website. There are hotspots to click to zoom in for more detail. Those maps as well as the Milky Way map are courtesy David Walbridge.
