The Ploo sector, a sector, resided within the Northern Dependencies of the Expansion Region. Within its boundaries were the planets Ploo II, Ploo IV, Plooriod III, Plooriod IV, and Serroco. A portion of the Greater Plooriod Cluster was also located there.
In the aftermath of the Battle of Endor, the Ploo sector was one of the initial sectors to break away from the control of the Empire.
