Sector Z-6 was a region of space. This sector encompassed the territory of the United Federation of Planets and the Romulan Star Empire. The Romulan Neutral Zone bisected this sector. On the Federation side of the zone, there were several outpost stations.
In 2293, the location of the Neutral Zone in the Milky Way Galaxy was depicted on the Federation star chart The Explored Galaxy. This chart was first seen on aboard the starship USS Enterprise-A. In the 2360s, the chart was seen again at Starfleet Headquarters on Earth, aboard the USS Enterprise-D, in a courtroom in the Starfleet outpost Starbase 173, and in a classroom on the space station Deep Space 9.
