The Tebru system, a star system, existed in the Outer Rim Territories' Juris sector. Within it was the rocky planet known as Tebru. During the time of the Galactic Civil War, Toria Tell, a droid collector, had a home on Tebru.
The StarWars.com Online Companion for The Essential Atlas reference book from 2009 was the first place the Tebru system was noted, specifically within grid square P-17.
