The Dalnan sector, also known as the Dalna sector, or as the Eiram–E'ronoh sector, was a sector in the Outer Rim Territories. It contained the planet Dalna, home of the Dalnan people. The Haileap system, containing the outpost Port Haileap, was situated at its edge. In 382 BBY, the Jedi Order increased its activity in the sector, much to the annoyance of "the Mother" as it disrupted her plans for the Path of the Open Hand.
During the Imperial Era, the bounty hunter Deva Lompop was based in the Dalnan sector.
