The Alderaan sector was a sector located in the galaxy's Core Worlds. It notably contained the planet of Alderaan, a peaceful and influential world, until its destruction by the Galactic Empire. It was represented in the Galactic Senate by Alderaanian figures such as Bail Antilles and Viceroy Bail Organa; and in the Imperial Senate by Princess Leia Organa who would go on to represent the sector in the New Republic Senate.
