The Valahari sector, also known as the Valahari Provinces, was a subsector of the D'Astan sector, in the Outer Rim Territories. It contained the planet Valahari.
The sector was the site of intense fighting during the Clone Wars.
Turr Phennir was born in the Valahari Provinces.
Jason Fry, co-author of the 2009 reference book The Essential Atlas, indicated during the development of the The Essential Atlas Online Companion that the Samarine and Valahari subsectors of the D'Astan sector present in the Online Companion were meant to be the Samarine and Valahari Provinces.
