- "The distress signal is coming from here—Meridian sector, Cybloc system."
- ―Obi-Wan Kenobi
A sector was an area of space or land framed by an artificial, conventional boundary.
A planetary sector contained a number of solar systems. Sectors were also regional political divisions. The galaxy was divided into a little over 1,000 sectors. Under the rule of the Galactic Empire, individual sectors were placed under the authority of a Moff, or sector governor. Several sectors could be regrouped into an Oversector governed by a Grand Moff.
Specific surface areas of a planetary body could also be partitioned into sectors. During the Clone Wars, the Confederacy of Independent Systems divided their territory on Anaxes into sectors, including Sector One.. The Outer Rim world of Batuu transported refuse from Black Spire Outpost to Sector 3263827.
